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:
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.
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.
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.
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.
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.

When your tire is underinflated, an icon, horseshoe-like with an exclamation point, illuminates on the gauge cluster of your car’s dashboard.
The technology responsible for giving out this alert is the tire pressure monitoring system (TPMS).
The TPMS gets information regarding their air pressure level from sensors. Depending on the type of TPMS installed in your car, the system may be relying on air pressure sensors inside your tires or the anti-lock brake system wheel speed sensors.
Why Do People Opt to Disable Their Tire Sensors?Clearly, these sensors are critical for your TPMS to work. But why do some car owners choose to disable their tire sensors?
First, you have to understand that sensors need to be in tiptop condition and mounted properly as well as reset accordingly to avoid false underinflated or overinflated tire alerts.
Yes, you read that right! Your TPMS may warn you that one of your tires do not have the correct air pressure level even if there is no real issue. There are various reasons for this, but the problem has something to do with the sensors most of the time.
For example, the TPMS warning light turns on when a relearn is not done after replacing your flat tire. In this situation, the system is still getting signals from the replaced underinflated tire instead of the new one. This is why you get an alert that you have a flat tire.
False TPMS warning alerts rarely indicate a major issue with your vehicle – one that diminishes its roadworthiness and threatens your safety. However, dealing with them can be inconvenient, annoying and even expensive since you might need professional help to resolve the issue.
These false alerts can also be distracting as the warning light stays on until the issue is resolved. This can be dangerous since a distracted driver is more likely to get in a car collision.
Inconvenience, annoyance, additional expense and safety hazards – these are just some of the reasons why a handful of car owners are disabling their TPMS.
Disable Tire Sensors – What Does It Mean & Can It Be Done?When people ask about disabling their tire sensors, what they actually want to know is if there’s a fuse that can turn off the TPMS.
Currently, the tire pressure monitoring systems installed in vehicles do not have an on/off button. Similarly, cars do not have a built-in fuse to stop sensors from transmitting information to the electric control module (ECM).
Due to the absence of an on/off switch, some employ crude methods to disable their TPMS.
For example, some choose to remove one of the sensors or forego buying a replacement when it gets damaged. It should be noted, though, that these options do not turn off the TPMS. In fact, doing these things is going to cause the warning light to stay on.
Others resort to putting black tape on the icon to resolve the issue of having an illuminated TPMS warning light. This way, they no longer see it and get distracted.
You are going to find other proposed methods of disabling the TPMS. But unlike the one mentioned above, these methods would require you to tinker with your car’s wirings or ECM. Apart from being complicated, these options can be risky because they can compromise the roadworthiness of your vehicle.
Now, is there a better way of turning off your TPMS?
Yes, there is a sophisticated yet non-invasive method of disabling your tire pressure monitoring system. All you have to do is use an emulator designed to bypass the TPMS.
The TPMS bypass emulator is a small box-like device equipped with technology to “turn off” your tire pressure monitoring system. Once it is activated, you don’t have to worry about the TPMS warning light turning on. Even if you have a damaged sensor or forget to relearn after changing tires, the warning icon is no longer going to light up.
With this device, it is as if you have a TPMS on/off button. Activate it and keep it in your car to disable the TPMS. Deactivate the device if you want to enable the system and get alerts about your tire’s pressure level.
It is also worth mentioning that the device won’t require you to manipulate any wires in your car or modify the ECM.
So, you don’t have to worry about making alterations that can interfere with the safety and performance of your vehicle.
In summary, you can disable your tire sensors or TPMS. There are different ways to do this, but it is best to choose a non-invasive and failproof method – using a TPMS bypass emulator. However, if you decide to disable your TPMS, make sure that you stay vigilant when it comes to the condition of your tires and regularly check their pressure level.

The TPMS system is designed to constantly monitor the degree of inflation of tires. Due to frequent errors or malfunctions, some drivers want to disable tire pressure sensors to avoid constant maintenance and problems.
Contents
1 Sensor reset button To understand how and why this is done, you should understand the design of the device and the principle of its operation. The skate inflation control system contains several interconnected blocks:
Principle of operation - pressure sensors monitor the degree of tire inflation in real time. When the boost drops below a predetermined level, the controller is triggered, the signal is sent to the block, where it is processed into pulses that are understandable for indication. Information is displayed on the dashboard.
The control system displays a malfunction on the panel by means of a special light bulb. The module signals to the driver that the pressure in one or more tires has dropped below the required level.
This may indicate the presence of a puncture or severe damage to the tire.
The design and operation of the sensors are primitive. To perform diagnostics of the part, it is enough to execute:
If the TPMS module icon does not go out, you will need to disassemble the wheels and examine the status of the sensors in detail. The sensor is removed from the seat and inspected. If there are no visual violations, and the element refuses to work normally, it is recommended to change the battery in the device case.
Note! On some types of sensors, the power supply cannot be replaced. Such sensors are replaced immediately.
Calibration is not required for most element types.
Devices from the factory are produced completely ready for operation. To activate them, you need to install them in the wheel and the system independently reads new sensors.
In some modifications, you will need to make pairings in manual mode. Each sensor has a serial number. It is driven into the corresponding menu field of the on-board computer, after which it is installed in the tire.
There may be several reasons.
The pressure sensor cannot be disabled by standard methods. There is no such option in the on-board computer.
A flashing and “cutting out” of a part of the program code is in progress.
Some BCs have this feature. To deactivate - you need to press the desired button.
When a flat tire is detected, the sensors will signal a loss of pressure. In some vehicles such as Toyota, the sensors are turned off forcibly. Practiced on off-road vehicles, where the tires are bled to make it easier to overcome obstacles.
The fault code is cleared automatically. To remove the indication, you will need to pump up the wheels to a predetermined level and drive the car for about 10 kilometers.
On some versions of the car, in order to reset the counter, you need to enter the settings menu on the dashboard. Then proceed according to the instructions.
To use the button correctly, first read the manufacturer's instructions. The button is located on the dashboard or near the steering rack.
If the indicator lamp appears and does not go out, there are two reasons.
It is possible for the indication to appear when the driver has put on the spare tire. Some machines have 5 sensors. If one of them is outside the vehicle, the system will consider it as a breakdown.
Causes:
On many vehicles, the option to force the sensors to turn off is not provided and is performed only by changing the software.
Leave feedback
1. What happens if I remove the sensors from the wheels?
A warning will appear on the screen. There is no way to get rid of this warning other than removing the sensor code from the driver display.
2. If one sensor in the system stops working, can I replace it?
Yes, each sensor has a unique identification code, just program a new sensor on the display, it will automatically replace the old one. But first, try replacing the battery.
3. Do I need to reprogram the sensors after a tire rotation?
No. The vehicle owner must rotate the tires after a certain mileage, but if the rims are used in the same places as before rotation, the display will not need to be reprogrammed.
4. Can the sensors interfere with each other?
Each INCAR TPMS sensor has its own unique code, just like each car has its own VIN number. The sensors send signals independently of each other, and it takes very little time to transmit the signal, so the chance of mutual interference is extremely low.
5. I am having trouble recognizing the sensor, what could be causing it?
This problem can occur when using an extension on the valve stem. First, remove the extension and install the sensor directly on the stem, this usually solves the problem.
6. Why is there no pressure or temperature reading on the LCD, only the tire icon is flashing?
Sensors transmit pressure and temperature every 5 minutes. The display will stop showing pressure and temperature if it does not receive a signal from the sensor for more than an hour. It's probably time to replace the battery.
7. How can I turn off the low pressure warning on the screen?
Inflate the tire marked on the display to the correct pressure.
8. The TPMS display gives a low pressure warning when I start the car, but after a few minutes of driving the alarm goes off.
In cold weather, the sensor receives a lower pressure value. As you ride, the air inside the tires heats up and the pressure increases proportionally. Try expanding the tire pressure range from the lower limit.
9. Will the sensor cause tire wear?
There are no problems with wheel balancing. On the contrary, due to the constancy of the nominal pressure in the tire, its wear will be minimal.
10. A few weeks ago I filled up the tires and everything was fine, but now the display shows me that the tires are low pressure.
Trust the INCAR TPMS sensors. Either the average daily temperature in your area has dropped due to the change of season, or there has been a natural air leak. First you need to pump up the tires.
11. Can the display be reset to factory settings?
Yes, to restore factory default settings, turn off the display, press the Set button and turn on the display.
The red indicator will turn off and the factory settings will be restored.
12. I have an alarm on the display, what should I do?
First, park in a safe place on the side of the road. Find out which wheel is causing the alarm by checking the icons on the display as well as the type of alarm. For example, it could be overpressure in a tire, which is related to base pressure settings - overheating can occur after a long break from driving on a hot day. Referring to the instructions, you will accurately determine the source of the problem and its exact location. Do not continue driving until the display returns to normal.
13. I received a low battery alarm, what should I do?
Eventually, all batteries run out. Three sensors from the INCAR TPMS range have replaceable batteries that can be easily replaced if needed. The CR1632 type battery is available from electronics stores or online. Two more sensor models do not allow you to change batteries - you will have to buy new sensors.
14. What is the display sleep mode?
If the display is left idle for more than 15 minutes, it turns off to conserve battery power. When it detects movement again, it will beep and the screen will come to life, indicating the exit from sleep mode. If the display was turned off overnight (which is optional), simply turn it on before leaving the parking lot and the tire pressure and temperature will be updated every 5 minutes again. Even if your display is in sleep mode, the INCAR TPMS system will always monitor the tires and will give an alarm if the pressure or temperature is no longer within the set parameters.
15. I receive a hard braking alarm, what should I do?
When the tire is under extreme load, a slow leak signal can be obtained. The fact is that at first the pressure in the tire jumps up, and then decreases over a short period of time. This situation is similar to a slow loss of air, and it often occurs when there is water inside the tire.
16. Everything works too well, how can I test the INCAR TPMS system?
The switched on display should be left in the driver's cab, and the sensors should be unscrewed one by one and re-tightened on the valve stem. The fast leak alarm should activate and then stop when the sensor is returned to the wheel. The beep is loud enough that you can hear it.
17. Are there any special recommendations for winter storage of INCAR TPMS equipment?
It's a good idea to remove the sensors and display from your car if it's been parked for a long time, especially in cold weather. Keep the system in a warm place, as you will significantly extend the life of the batteries. Number the sensors or put them in an egg carton so they can be put back on the same wheels. This way you avoid having to do a new setup. The sensors do not use power unless they are mounted on the wheel.
18. How will the driver's display behave if the sensors are installed only on part of the car's wheels?
The INCAR TPMS cycles through the tires.
As the cycle progresses, the tire symbol flashes on the display to indicate that that particular tire is being tested. You will see the exact pressure and temperature for that tire. The display will then automatically move to the next wheel on which the sensor is installed. You will only get readings for tires equipped with sensors, the rest will be skipped and will not take time.
19. If you shake the driver display, you can hear something small rattling inside.
This is not a standard situation. If you feel that there is something wrong with the display, or if this sound annoys you while driving, you should have the equipment examined by our experts. But first, check the charging port on the left side to make sure it's safe.
20. How can I turn off the backlight of the display?
The backlight cannot be turned off manually as it is controlled by the ambient light sensor, but you can unplug the power cord and the backlight of the display will turn off automatically to conserve battery.
21. My display says that the tire pressure is 5 atm, and the pressure gauge shows 5.5 atm. What does this mean?
INCAR TPMS has been tested and certified by an external laboratory with a pressure measurement accuracy of 0.1 atm. Perhaps the sensor does not receive full contact and, accordingly, full pressure, in contrast to the pressure gauge. If the other pressure gauge also shows a discrepancy, and the measurements are taken in the morning before the trip, you need the help of a specialist.
22. After one year of operation, the two rear tires on the trailer are no longer permanently available to the display and the display shows less information about them. Why is this happening?
Please write to us at the contact address or call us, we will help you solve your specific problem. Perhaps your trailer began to interfere with the reliable passage of the signal from the sensors, or the batteries simply ran out of them, which significantly weakened the signals from the sensors.
