Whenever your car says service tire monitor system, this means that more than likely you have a bad tire pressure monitor sensor (TPMS). Don’t worry this light isn’t going to hurt your car at all.
This warning is just letting you know something is wrong with the TPMS. A TPMS or service tire monitor system, just lets you know when your tire pressure is too low or too high.

Tire pressure monitor sensor activation tool is simple and fast. It activates the individual TPMS sensor with the press of one button. It can easily be done within 1-2 minutes, saving you $20-$80. Much better and faster way to fix your sensors than going to the dealer.
The service tire monitor system is the sensor and the TPMS Module.
You more than likely just have a bad TPMS sensor or sensors. That’s right, I said sensors. Your vehicle has a total of four sensors. This is true if you are driving the standard four wheel vehicle (one per tire). You’re probably wondering where these sensors are located right?

TPMS SensorWhere is the Service Tire Monitor System?These sensors are located either on your valve stem inside your rim, or on the rim itself on the opposite side of the valve stem. If located on the opposite side of the valve stem, the sensor is mounted on a band that’s wrapped around the rim. The TPMS sensor is located in each tire.
Before you put a new sensor in, it is recommended that you check your tires for correct PSI and then check the sensor.
Checking the sensor is super easy and affordable with a TPMS Relearn Tool. This tool properly tests the status of your TPMS sensor detecting if the sensor is good or faulty.
With this tool you can feel safe knowing your tires are properly inflated and that your TPMS light is coming on when it should.
You can fix a tire sensor fault. All you have to do is get a TPMS scan tool to figure out which sensor is bad or sensors. Then let all the air out of your tire(s) with a valve core remover tool.
4 steps to fix TPMS
If replacing your TPMS sensors does not fix the problem then you most likely have a bad TPMS module. A TPMS module going bad is really rare compared to how often TPMS sensors go bad.
However, if you just had your tires replaced and they put new sensors in make sure they programed your sensors to your car with your TPMS scanner.
Why is My TPMS Light On?Your TPMS light comes on when your tire pressure is too low or too high. This light is basically there to alert you of unsafe driving conditions brought on by your car or truck’s tire pressure.
However, the sensor itself could be faulty.
To fix this it’s simple, all you need to do is air up your tires to the correct pressure, indicated by your vehicle’s identification sticker, and retrain the TPMS sensors. Usually, all you need to do to reset this light is drive the car (after airing your tires), but sometimes your car may require a TPMS sensor scanner.
If you check your tires PSI and they are all as they should be, then your TPMS sensor is bad.
Always make sure you have the correct tire pressure in your tires. You don’t want your tires wearing uneven and risking the chance of having bad tires prematurely.

Service Tire Monitor System LightWhy is My Low Tire Pressure Light on But My Tires are Fine?If your tire pressure monitor sensor light is flashing or staying on but your tires are fine, this means you more than likely have a dead or broken sensor. If that is the case you will need to scan your TPMS sensors to see which sensor has gone bad.
Using the best cheap TPMS scan tool this is super easy.
HOWEVER, if your sensor isn’t bad, and your light is solid and not flashing, you just need to check your air pressure, more than likely the sensor is doing its job and alerting you that your tire PSI is not correct.
That means the PSI for that tire is too high or too low. If your low tire pressure light is on and all your tires have equal PSI to each other, this means you probably just need to air up all your tires.
If there is a tire that is way lower than the rest you need to inspect the tire for a tire leak. Once you fix the tire leak and air up the tires, or if your tires are low and you put air in them, you need to retrain your TPMS sensors.
Sometimes, this means you just need to drive the car. Sometimes you need a TPMS scanner to reset the tire pressure monitor sensor light.
How Does a Service Tire Monitor System Go Bad?Well there could be several reasons as to why your tire sensor is bad or is going bad.
You could have a dead service tire monitor system. There is a battery inside your TPMS sensor that usually will die after six years. Sometimes, these batteries will fail prematurely.
The other reason your sensor could be bad is because when someone put your new tires on, they broke the TPMS sensor. If this is the case you need to take it back to where you had the tires installed and get them to replace the sensor they broke.
Note: To be clear, your TPMS sensor is the only thing that has the battery that goes dead. The module would just go bad due to age.
So, it is always a good idea to have the knowledge and proof of knowing if your TPMS light was working correctly before you took it in the shop to get new tires.
If broken during the tire change or replacement, the TPMS light will appear flashing on your dash shortly after leaving the shop (if it is not already upon re-entering your vehicle).
On the other hand, if you don’t trust the place you went to, or are planning on going to, you can scan and replace the sensors yourself.
With the proper tools of course.
How Much Does it Cost to Replace a Tire Pressure Sensor?Pro Tip: Why risk your safety for someone else’s lack of effort?
Tweet
The price of a service tire monitor system can vary depending on brand and where you purchase the sensor. If you replace the sensor yourself you’re looking $50 or less for all four sensors. If you take it to a shop, it will probably be $100 for literally 5 minutes worth of work.
They will charge you to take off your tire (when they never actually take it off). They simply break the top bead of your tire and unscrew the sensor.
Why pay someone 1000’s of dollars to replace your tires and sensors, when you could do all of this yourself. Plus, you can save a ton of money by buying the parts you need online.
Can I Drive With My TPMS Light On?This has always been a big question, is it safe to drive with a TPMS light on.
The answer is yes, it is safe, BUT always make sure that your tires are aired to the correct pressure.
Also, be sure there isn’t something causing your tire to leak. It is always good safety practice to inspect your tires before driving. Learn to fix your tires yourself.
All the TPMS light is doing is making sure you know your tire pressure is either too low or too high. So, as long as your tires look fine and pass your tires recommended PSI, you’re safe to drive.
Be sure to air your tires up to the correct pressure. Also check/reset your TPMS light before driving to prevent a wreck.
How Long Does It Take For the TPMS Light to Go Off?Resetting a service tire monitor system light is simple. Sometimes it’s as easy as just airing up your tires to the correct pressure and driving the car for 20 minutes.
In other cases, you will need a TPMS light scanner. This tool will reset the TPMS light for you all you need to do is adjust your tire pressure.
If you are unsure of where to look for the correct tire pressure open your driver door and look at the door frame. There will be a sticker that will tell you the correct tire pressure for your car.
After you air up the tires, punch in your vehicle’s information in the scanner and the tool will walk you through the process. It’s that simple.
How to Test a Service Tire Monitor System BatteryIn order to test your TPMS sensor battery, you need to get a TPMS scan tool. Simply scan the sensor through the tire. The TPMS scan tool will tell you how much battery life you have in your TPMS sensor.
Usually when your tire sensor is dead your TPMS light will be flashing, the tire pressure sensor fault/ tire monitor pressure system will display a fault. That fault will be written across the display screen.
Mechanic Mike Says:
“Sometimes when a tire sensor starts to go bad or is bad your tire light will cut on and off. Meaning its battery is dying.
”
Here are some symptoms of a bad TPMS sensor. Your tire light may come on and turn off randomly and your tires will be at the correct tire pressure. The TPMS light cutting off and on means your service tire monitor system battery is probably dying.
Your tire light flashing can also mean you just have a bad TPMS sensor. This means you do have a bad sensor somewhere. If you get a warning on your display screen that says tire pressure monitor system fault or TPMS sensor fault this means you have a bad service tire monitor system. You will need a TPMS scan tool to figure out exactly which TPMS sensor is going bad. Using the scan tool, program your new tire sensors.

The article says:
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.
American and European scientists conducted a study in 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.
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.
2 bar. 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.
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.
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:
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.
Why such problems may occur:

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.
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.
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.
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.

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.
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 blink 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.

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 must 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.
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.
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.
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.
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.
TPMS or Tire Pressure Monitoring System is a set of equipment commonly found in modern cars. Its main job is to alert you if there are problems with tire pressure. For example, one tire has lost pressure - in this case it is not safe to drive, but the system will inform you about this, and you can inflate the wheel to avoid steering problems.
But sometimes the system does not work correctly.
Some sensors may fail or the system needs to be rebooted. In this case, you may see a blinking or simply lit tire pressure error indicator on the dashboard. Resetting the pressure monitoring system will help you solve the problem if the sensor is working.
Please note that different vehicles may have different TPMS reset methods, so you may need to try several of them before you know the most effective one.
Initially, you will just need to hold the tire pressure sensor reset button for a few seconds until the pressure indicator flashes three times and then turns off. But sometimes it doesn't help much. So we found other ways to calm down the pressure control system.
First, locate the TPMS reset button, which is usually located somewhere under the steering wheel. Start the car, press and hold the button for 3 seconds. Then drive at a speed of 80 km/h for approximately 10 minutes. Of course, you will need to find a suitable track for this.
Steady driving is an important part of resetting tire pressure sensors this way. Of course, before this operation, you will need to inflate the tires to the required pressure.
In some vehicles, you will need to drive on any road and at any speed for 20 minutes after resetting the sensors, as long as you do not turn off the engine.
So, start the car, press the reset button and hold it for three seconds. Do not turn off the engine until 20 minutes have passed. You can drive or just let the engine idle for 20 minutes. This method of resetting the pressure sensors should work for most vehicles. Again, inflate the tires to the correct pressure before resetting the system.
If the simple methods don't work with your machine, try another method. Start the engine so that the tire pressure monitoring system can register the changes. Then inflate the tire 0.2 bar above the recommended level. After a minute, completely deflate the tire.
Wait one more minute to reset the sensors. Then inflate the tire to the optimum pressure level and let the engine run for another minute. The indicator should stop flashing.
The idea is to reset the entire engine electronics system by cutting off the power supply from the battery. First, make sure all tires are at the correct pressure. After that, turn off the engine, open the hood and disconnect both terminals from the battery. Wait 10-15 minutes. Reconnect the battery and turn on the ignition to check if the indicator lamp goes out.
If the above methods do not work with your vehicle, there is another option. Find a manual for your car or open a forum thread that talks about resetting tire pressure sensors in your car. Look for the combination of steps the manufacturer recommends to reset the TPMS system. Sometimes the combination can be quite strange and even complex.
If all methods fail and the error light continues to flash, the problem may be with the sensors.
It is the blinking signal of the tire pressure lamp that often indicates a sensor malfunction. If there is a problem with tire pressure, usually the light will just come on and not blink.
So if the light is flashing, one of the sensors may be faulty. Replacing the element is not so easy because it is under the tire. The tire must be removed from the rim to replace the sensor.
After replacement, you will still need to reset the pressure control system for the new sensor to work. Otherwise, the indicator will flash or light up.
Where is the reset button for the tire pressure sensors?
The button is often located directly below the steering wheel. But there may be different options. If you don't find the TPMS reset button there, look around the steering wheel - it should be somewhere in this area.
Difficult to say for all vehicles, but for most vehicles, the travel time before the tire pressure monitoring system resets should be at least 10-15 minutes.
If you turn off the engine earlier than 10 minutes after pressing the reset button, the TPMS will still send some error signals the next time the engine is started.
Drivers occasionally upgrade tires and wheels to larger ones and want their stock pressure control modules to work properly. The problem is that larger or flat-ride tires will have a different optimum pressure level, so the original gauges will always show an error on your dashboard.
One way to solve the problem is to buy other sensors adjusted to the correct tire pressure. Another way is to reset the control system in your car at the service station. Just check which option will be cheaper for you.
It's hard to say why manufacturers haven't added an option to automatically reset tire pressure sensors in cars. In most post-2015 vehicles, the TPMS is autonomous enough that it won't bother you much with reset requests.
