Your tire pressure light provides a critical reminder to restore the pressure in your vehicle's tires when it gets low. You should only attempt to reset the light after first addressing the tire pressure in every tire. Once your tires are at the appropriate pressure, the light may go off on its own. If it doesn't go off right away, driving at 50 mph for about 10 minutes should help the tire pressure sensor reset.

If the tire pressure light is still on, there are a few more tricks you can try:

  • Turn the car key to "on" but don't start the vehicle. Press and hold the TPMS reset button until the tire pressure light blinks three times. Release the button and start the car. The light should go off within 20 minutes.
  • Disconnect the positive battery cable while the vehicle is off. Turn the car on and press the horn for three seconds to discharge the remaining power. When you reconnect the battery the tire pressure light should be off.
  • Overinflate all the tires (including the spare) with 3 PSI, then deflate them completely. Re-inflate the tires to help reset the light.
  • Bring your vehicle to our service center for professional assistance.

IS TPMS the Same as Tire Pressure Light?

 TPMS stands for Tire Pressure Monitoring System. The tire pressure light is one component of this electronic system, providing a visual alert when your tire pressure is low. The TPMS monitors tire pressure using either an indirect or direct method.

An indirect TPMS measures the rate of revolution for each wheel. If a wheel starts spinning faster than anticipated, the system signals to your vehicle's computer that something is amiss with the tire rotation, and your tire pressure light comes on. You must manually reset the monitor in an indirect TPMS system.

A direct TPMS uses pressure monitoring sensors in each tire to monitor tire pressure exactly. This is a more accurate alternative to an indirect TPMS system. The batteries inside these sensors will last for about 10 years. Direct TPMS systems reset automatically after tire inflation or rotation. You do need to have these sensors resynchronized when you get new tires, which requires a special tool.

Can Cold Weather Cause Your Tire Pressure Light to Go On?

Yes, cold weather will affect the air pressure in your tires. Your tires lose one or two pounds per square inch (PSI) for every 10 degrees that the temperature drops. Cold air condenses while warm air expands. Therefore, the colder air in your tires will take up less space in lower temperatures.

You may find that your TPMS light is only illuminated for a short time in the morning on particularly cold days. After about 20 minutes of driving, the air will often warm up and expand, restoring proper pressure in your tires. If the light stays on after 20 minutes on the road, you should add air to your tires as needed to restore the proper pressure. Low tire pressure is hazardous for your vehicle regardless of the cause.

Why Is My Tire Pressure Monitor Light On When My Tires Are Fine?

When the tire pressure monitor light is on, the first thing you should do is check the pressure in each of your tires, including the spare. Check the manufacturer's recommendation to determine the appropriate pressure for each tire. This is typically between 30 and 35 PSI but may vary. You should measure tire pressure when the tires are cold, which means they have not been driven in the last three hours.

To check the pressure, simply unscrew the valve cap and insert a tire gauge into the valve stem. The gauge will provide a clear reading. Replace the valve cap when you're finished. If your tires are all at the appropriate pressure, there's a malfunction with your TPMS. Bring your vehicle to an authorized dealership service center to diagnose and resolve the issue.

Is it OK to Drive With My Tire Pressure Monitor Light On?

If the tire pressure monitor light is on, you should check your tire pressure as soon as possible. Low tire pressure creates a serious hazard on the road. According to the National Highway Traffic Safety Administration, 738 people died in tire-related crashes in 2017. When tire pressure is low, the tire has more contact with the road. This may cause the tire to overheat, leading to tread separation, excessive tire wear, or a blowout.

Low tire pressure also wreaks havoc on your fuel efficiency. You can save up to 11 cents per gallon simply by keeping your tires properly inflated. You'll also save money on tire replacements with adequate inflation. Keeping your tires properly inflated can add 4,700 miles to the tire's average lifespan.

The tire pressure monitor light gives you valuable information and should not be ignored.

Do I Need to Replace My TPMS When I Get New Tires?

You do not necessarily need to have your TPMS sensors replaced with new tires, but this is a good time to check them and make sure they're still in good condition. If you have an indirect TPMS system, your mechanic will need to manually reset the sensors after changing your tires. If you have a direct TPMS system, no additional maintenance is required to reset the system.

A new TPMS system will typically last for about 10 years before the batteries run out. If you have an older vehicle, you may need new sensors every five or six years. Your mechanic can advise you on the best time to replace TPMS sensors for your vehicle. When new sensors are installed, the system must relearn the location of each tire, which requires a detailed series of technical procedures. You should leave this task to a professional.

How Do I Get My Low Tire Pressure Warning Light to Turn Off?

171 Washington Street, Morristown, NJ | 973-540-9880

by alazo@eaglesoars. com

Another pesky light is illuminated on your dashboard. This time it’s the low tire pressure warning light. Fixing the problem could be as simple as adding air to your tires. What do you do if you’ve checked the tire pressure and it’s fine? Read on to find out about your vehicle’s Low Tire Pressure Monitoring System – why you need it, how it works, and what you should do when this warning light comes on.

Why Does My Car Need a Low Tire Pressure Monitoring System?

Your vehicle is equipped with a Low Tire Pressure Monitoring System (TPMS) to help you make sure your tires are inflated to the correct air pressure. Almost 200 deaths occur each year because of tire-related crashes and a good number of them happen because tires are underinflated. Think about this for a moment. When was the last time you checked the air pressure in your tires? Do you check your tire air pressure once a month, as is recommended? The TPMS makes the job a little easier for you.

Ok, So I Need a Low Tire Pressure Monitoring System, but How Does it Work?

Your car is either equipped with a direct or indirect TPMS. The sensors in a direct TPMS monitor the air pressure within each of your tires. If the tire pressure in one or more of your tires drops 25% or more, the computer module in your vehicle will trigger the tire pressure warning light on your dashboard. With an indirect TPMS, wheel speed sensors are used to determine how fast your tires are rotating in comparison to the relative size of your tires. If a wheel starts to spin faster than it should, your car’s computer assumes the tire is underinflated and it tells the TPMS warning light to illuminate.

The Tire Air Pressure Warning Light is On. Now What?

  • If it Comes on While You’re Driving: If you’re driving and the TPMS comes on, pull over to a safe place and stop to check your tires. Unless your tire is completely flat, you’ll want to use a tire gauge to check the tire air pressure in each tire. You can find the correct tire air pressure on the label found inside the driver’s side door panel or in your vehicle owner’s manual (do not use the air pressure identified on the sidewall of your vehicle’s tires). If one or more tires is low, re-inflate them. (Click here for information on how to care for your car tires.)

Quick Tip: Always carry a tire gauge in the glove compartment so you can quickly check the air pressure once a month. Remember, to check the tires when they are cold – first thing in the morning is best.

  • If it Comes on In Cold Weather (in the morning or before you start driving): The air pressure in your tires will drop when the temperatures are colder. In fact, the colder the temperature, the more the pressure will drop. If the tire air pressure falls 25% or more, the TPMS dashboard warning light will come on. You’ll need to add air to your tires, but be careful not to fill them too much as the air in them will expand once the tires warm up.

Quick Tip: Some vehicles are equipped with a reset button for the TPMS Warning Light. Once you’ve filled the tires to the correct pressure, reset the warning light on your instrument panel.

Why Does the TPMS Warning Light Stay On or Come Back On After It’s Been Reset?

If you’ve added air but the air pressure warning light stays on, there’s a problem with your Tire Pressure Monitoring System or you have a slow leak. Assuming there is no leak in your tire, a lit TPMS warning light indicates a problem with a tire pressure sensor. One of them may be bad, the lithium-ion battery may be dead or there could be an internal fault within the TPMS. In any of these cases, you’ll need to have repair work performed on your Tire Pressure Monitoring System.

Quick Tip: If the TPMS warning light comes back on after you’ve filled the tire with air, recheck the tire to make sure it is inflated to the proper air pressure. If the tire air pressure is low, you have an air leak and should have the tire fixed or replaced.

How to reset a tire pressure error: a few easy ways

Save article:

The article says:

  1. Why you need a tire pressure sensor
  2. What are the reasons for triggering the sensor
  3. How can I reset the tire pressure sensor error
  4. How to adjust tire pressure sensors

When the tires are optimally inflated, the low tire pressure indicator (TPMS) does not light up on the vehicle's dashboard. However, in some cases, it lights up even if the pressure is normal. This can't help but be annoying, especially when the tires are inflated normally. In our article today, we will figure out how to reset a tire pressure error. nine0003

Why do you need a tire pressure sensor

American and European scientists conducted a study, during which it was found that most drivers do not check whether the wheels are properly inflated before getting behind the wheel of a car. Only 40% of car owners perform such a check - and even then only once every 12 months. This is the reason for a large number of accidents.

The TPMS (Tyre pressure monitoring system) system is designed to monitor tire pressure, as well as warn of a malfunction. If the tires are under-inflated or over-inflated, an error will be displayed on the remote control or an audible signal will appear. nine0003

What is dangerous too high or, conversely, low pressure? The risk of an accident increases, the car begins to consume more fuel, in addition, the rubber wears out faster.

The above devices operate on the same principle. Let's figure out how information about what tire pressure gets to the control panel.

  • Each wheel is equipped with a controller. It records tire pressure data. nine0008
  • Information is transmitted from the sensor to the transceiver with a frequency of 2-3 seconds . The controller transmits data using Bluetooth.
  • The program analyzes the received data, which should correspond to normal values ​​ . Otherwise, when the tires should be lowered a little, the program sends a signal to the car owner. Exactly according to the same principle, a signal is transmitted if the rubber needs to be pumped up.
  • Depending on the device, the error signals are sound, as well as light .
  • The driver can set the operating parameter limit himself . As a standard, the automaker makes it possible to adjust the device from 1.7–3.2 bar.
  • On some car models, the TPMS system sends data to your phone.

Consider how pressure is calculated by measuring instruments. Typically, the sensor performs a comparison of the angular rotation of the wheel. Knowing the value of this parameter, you can calculate the distance that the wheel will travel in one rotation. nine0003

Obviously, if the tires are under-inflated or over-inflated, then the outer diameter of the wheel will be different. Visually, a person cannot determine this change. But the sensor notices even such changes. The system fixes non-compliance with the required parameters.

Causes of tire pressure sensor activation

The sensor will still respond, despite the fact that the wheel circumference has changed quite a bit. In this situation, it is necessary to find out what mechanical reason led to this. Only in this way can you eliminate the misinterpretation of the signals transmitted by the system. This can happen because: nine0003

  • Tire not inflated enough.
  • You have fitted a different wheel with a different shape, dimensions and tread.
  • A “spare wheel” was supplied, it also differs in parameters from other wheels.
  • Rubber has been punctured or torn.
  • There is an uneven load on the car, as a result the car is skewed to one side.
  • You have installed anti-skid chains on the wheels.
  • nine0007 An overload of one of the axes has occurred; this happens when you are driving uphill or downhill, towing a trailer.

Also, the TPMS system gives an error when you install new wheels or rearrange them.

When, after these steps, a tire pressure error appeared, indicating unbalance, you should reset the settings, and then set the basic parameters. In this case, the control signal may remain even if the basic settings have been selected. nine0003

Why such problems may occur:

  • Different tire pressures . Some wheel is under-inflated or vice versa.
  • The error occurs because a system crash has occurred . It will only be possible to reset it at the service station.
  • The indicator lights up when you operate the car using a sporty driving style, driving on ice, dirt road . At the same time, as soon as you drive out onto an asphalt surface or start driving calmly, the error disappears. nine0008

How to reset tire pressure error? To begin with, imagine that the TPMS system is working properly and the blinking light indicates a problem with the undercarriage of the machine. The first thing you should do is slowly release the gas. You can not brake sharply, turn the steering wheel. After the car has stopped, inspect the tires to make sure the rubber is not punctured or broken. Then you can check if the tire pressure is normal. nine0003

Pay attention! The TPMS will not always show a tire pressure error. For example, if the tires are slowly deflating, the system will not inform you about the problem. In the same way, she will not notice the error if the tire pressure starts to drop rapidly. This usually happens when a tire ruptures. This feature of the TPMS system is explained by the specifics of identifying and counting nonconformities.

However, in some cases, it happens that the TPMS system indicator is on, but the tires are in perfect condition. How to reset tire pressure error? We understand. nine0003

A few simple ways to reset the tire pressure sensor error

The complex TPMS system in some cases starts to work incorrectly. Usually, car owners observe the following picture: a tire pressure error is displayed on the display (the tire is underinflated), but in reality everything is fine with the wheel. You have to reset the tire pressure error. Otherwise, the TPMS system starts to work incorrectly.

You also have to reset the tire pressure error when there is radio interference from high voltage power lines. Or when sources of radio signals are located in the immediate vicinity. But as soon as you move away from them, the pressure error disappears and the system begins to function properly.

The reason for the malfunction may lie in the sensor, which is "failed". This damage cannot be easily repaired. How to reset a tire pressure error if the sensor flashes, while you hear a beep, lose your vigilance and find it difficult to drive a car? There are 4 ways to fix this problem. nine0003

Method 1

To reset the error, pick up a speed of 80 km / h and continue driving for another 15 kilometers.

This method is the easiest to implement. If your car has this feature, then turn on the cruise control so that the speed does not change. Depending on the model of your car, you will be able to reset the tire pressure error at a speed that exceeds the specified one. After you cover a distance of 15-20 kilometers, maintaining the same speed of 80 km / h, make a stop. Turn off the motor. When you start it again, the tire pressure error will disappear. nine0003

Method 2

Press the tire pressure monitoring system (TPMS) reset button on your car and you will be able to reset the error.

It does not matter what type of low pressure warning system is used. In any case, there will be a sensor on each wheel of your car. Sometimes it may be necessary to reboot the touch system of the car. Read the owner's manual for the vehicle. It contains information on how to reset a tire pressure error. Most often, the instructions indicate which button to press to reset. nine0003

The ignition key must be in the lock. No need to start the car, just turn it to the “on” (“ON”) position. Then press and hold the reset button, which may be under the steering wheel. We are waiting for the low pressure indicator to flash 3 times. After that, you can release the button. We start the car, it should work for 20 minutes. After this time, the computer will calibrate the sensors on the wheels. Now you can turn off the car.

Method 3

Lower and then re-inflate the wheels.

Failed to reset tire pressure error using the previous method? Then we inflate all tires to 0.2 bar, this is the pressure that should be according to the recommendations of car manufacturers. Did the error go away? Then we lower the pressure in the tires completely.

Now we pump up the wheels again. The pressure in them should be the same as indicated on the driver's door pillar or in the car's operating instructions. When there are sensors on the wheels, you need to remember about the spare tire. Now you need to drive about 3-5 kilometers, adhering to a speed of 25 km per hour. So you can reset the tire pressure error. nine0003

Method 4

Remove the battery terminals and then connect it to reset the error.

Each car has a computer that receives data from all kinds of vehicle sensors, including TPMS system sensors. However, any electronics can fail. To reset the error, you will have to reboot the system, for which you need to turn off the power.

To do this, open the hood. The battery is located under the hood. Disconnect the negative terminal from it. To perform this operation, use a wrench. Then sit in the driver's seat, turn the key to the "ON" position, but do not start the car. Now you need to press the signal for 3 seconds. This will use up the energy that remains in the electrical system of the machine. Then reconnect the battery. This way you can reset the error. nine0003

How to adjust the tire pressure sensors

Sensors keep track of tire pressure. However, you need to be sure that they function properly. Of course, you do not need to constantly walk around with a special measuring device and find out the status of the sensors. It just needs to be calibrated from time to time.

It is performed quite simply. The most important thing to remember is that, depending on the make and model of your car, for each wheel there are pressure parameters strictly defined by the manufacturer for winter and summer. These values ​​should be given to the sensors. How the installation and configuration will be performed depends on the controller used. nine0003

  • Mechanical controller . It is convenient to use. We just screw it in instead of the cap. Nothing else needs to be configured.
  • Electronic controller . The installation procedure will be more difficult, because the device has a control unit. It can work autonomously or you will need to connect it to the cigarette lighter. We turn on the device in the training mode. Then proceed according to the tuning algorithm that is set by the manufacturer. You will have to put the device on all wheels, starting from the left front. Once the installation is done, make sure that all gauges are correctly displayed on the monitor. Otherwise, you will have to rearrange them so that everything matches the parameters on the display. nine0008
  • Internal controller . Such devices are the most difficult to mount, because for this you will have to use special equipment for tire fitting. Experts do not recommend using the internal controller yourself. However, additional settings are not required if the data is read using the screen that is directly on the control system.

For current promotions on the Halva card, which will help you profitably purchase household appliances, you can follow here. nine0003

To prevent a tire pressure error from appearing, it is important to calibrate (adjust the TPMS system) every time a change is made. For example, when you installed a new set of wheels, repaired tires, did balancing, and the like. Using TPMS controllers is quite simple. The main thing is to read the instructions for use of the device. And make sure that the tire pressure is the one recommended by the car manufacturer.

Every car owner gets annoyed if the tire pressure error icon lights up on the dashboard. This indicator informs you that something is wrong with the wheels. However, even if the tire pressure is optimal, the tire pressure error must be reset.

The fact is that if the TPMS system icon constantly signals insufficient pressure, the driver will not be able to know when the rubber will actually begin to deflate. Driving becomes dangerous for both you and other road users. It is necessary to find out the cause of the malfunction as soon as possible and reset the tire pressure error. This is the only way to operate the vehicle safely. nine0003

The Japanese crossover Mazda CX5 was the first car of the Skyactiv Technology concept. It declares high safety criteria while reducing the total mass of the vehicle. In accordance with this concept, even the basic Mazda CX5 was equipped with tire pressure monitoring sensors, as well as other safety protections. nine0003

Why check tire pressure?

Worn-out tires are the catalyst for many accidents, and the most serious tread damage occurs with over-inflated or flat tires. In the first case, the center of the treadmill burns out - because of this defect, the stopping distance and the number of accidents during emergency braking increase. In the second case, the edge of the tread is erased - this defect leads to a loss of traction when maneuvering.

However, incorrect tire pressure can lead to unpleasant consequences not only in the long term. A car driver who ignores the signals of the wheel control system faces the following problems:

  • loss of dynamics - it will no longer be possible to accelerate to 100 km / h in 7-10 seconds;
  • decrease in controllability - the car skids when cornering even on a dry road;
  • increase in fuel consumption - instead of the expected 4. 6-9.8 per 100 kilometers, the Mazda CX5 will “eat” up to 8-12 liters.

If ​​the tire pressure monitoring sensor on the dashboard is on, do not ignore it, but try to deal with the problem.

How does the Mazda CX5 tire pressure monitoring system work?

The wheel control system can be direct or indirect. The first technology relies on controllers built into the tire. The second system operates with data on the size of the wheel and the associated angular velocity. The designers of the Mazda concern opted for an indirect TPMS system. nine0003

The main components of the TPMS system are software and four sensors that control the angular speed of the wheel. A flat or over-inflated tire changes its outer diameter, which decreases or increases cornering speed. The control sensor checks this indicator while driving, and the software compares the received data with baseline values. If the basic values ​​deviate, the signal “Tyre pressure error” lights up on the dashboard.

In order for the TPMS system to work, you need to initialize the software and sensors. Without prior activation and calibration, the number of false positives increases (the signal will be on even if the tire is properly inflated).

How to Initialize a TPMS System - Step by Step Guide

  1. Inflate all four wheels of your Mazda CX5 to the recommended inflation pressure. For R17 tires, the recommended figure is 2.3 bar, for R19 - 2.5 bar.
  2. Insert the key into the ignition switch. Turn it to the ON position and return to LOCK. This will activate the onboard network to which the air control system is connected.
  3. Please wait at least 15 minutes. During this time, the on-board computer will catch the sensor signal, read its ID and register the bus controller. If you want to play it safe, wait 20 minutes. nine0008
  4. Start the vehicle, drive off and accelerate to 25 km/h. Maintain this speed for 10 minutes while driving on a level road.
  5. Check the TPMS indicator for correct pressure. If an error signal is on on the panel, press the TPMS SET button, which will reset the controller binding. After the reset, repeat the binding according to the described scheme.

When does the control system fail?

An indirect TPMS system is not one hundred percent reliable way to control pressure. It happens that it gives an error in which the signal is on, and the pressure in the wheel is normal. Most often, such a failure occurs when tires of different models are installed on car rims.
