How to Effectively Troubleshoot 5 Common TPMS Errors

Understanding and Troubleshooting the TPMS Light not Turning Off

The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in modern vehicles, designed to alert the driver when the tire pressure is too low. One common error with the TPMS is the light not turning off, even after the tires have been adequately inflated. This persistent issue may be due to a faulty sensor in the TPMS, a damaged antenna, or a mere communication malfunction within the system.

To troubleshoot this error, start by checking the tire pressure manually using a reliable gauge. If the pressure is within the recommended range and the TPMS light still doesn’t turn off, reset the system following the vehicle’s manual instructions. If the problem persists, it’s advisable to inspect the TPMS sensors. Over time, the sensors can wear out or get damaged, thus failing to communicate correctly with the system.

Remember, each wheel, including the spare one, has a sensor. Therefore, make sure to inspect all. To access the sensors, demount the tires or consult a professional if you lack the necessary skills or tools. Should the sensors be in good condition and the TPMS light doesn’t turn off, consider checking the TPMS module and antenna. These components could be damaged or have a loose connection, preventing the TPMS from functioning correctly.

Causes and Solutions for TPMS Light Blinking

Sometimes, the TPMS light may start blinking before becoming steady. This TPMS error often indicates a malfunction in the TPMS itself rather than low tire pressure. The main causes of this error include a dead TPMS sensor battery, a malfunctioning TPMS sensor, or an issue with the TPMS module.

Firstly, check if the TPMS sensor batteries are dead. These batteries typically last between 5-10 years, and when they die, the TPMS sensor cannot communicate with the vehicle’s computer, causing the TPMS light to blink. Unfortunately, most sensors’ batteries are built-in, meaning you’ll have to replace the entire sensor. You can find a variety of TPMS sensors on platforms like Amazon.

Secondly, check for a faulty TPMS sensor. These sensors can fail due to physical damage, exposure to harsh environmental conditions, or just wear and tear over time. To check the sensors, you may need a TPMS tool that can read sensor data. If the tool can’t detect a sensor, it’s likely faulty and needs replacement.

Lastly, if the TPMS module, the system’s control unit, is faulty, it may not read the sensors correctly, causing the TPMS light to blink. A professional mechanic should inspect the module to determine whether it needs fixing or replacement.

TPMS Signal not Being Received: A Comprehensive Guide on What to Do

At times, the TPMS may not receive a signal, making it unable to monitor the tire pressure accurately. This error can be caused by sensor failure, signal interference, or an issue with the TPMS antenna or module.

Begin troubleshooting by checking the TPMS sensors. Over time, the sensors can wear out or become damaged, causing a signal failure. Make sure to inspect all the sensors, including the one on the spare tire. If the sensors are functional but the TPMS is still not receiving a signal, inspect the TPMS antenna and module. These components might be damaged or have loose connections, thus affecting the signal reception. A professional mechanic can help with these inspections and repairs.

Signal interference is another common reason for the TPMS not receiving a signal. This interference can be from devices transmitting at the same frequency as the TPMS, like certain types of electronic devices, or even from other vehicles’ TPMS. If you suspect signal interference, try moving the vehicle to a different location and see if the problem resolves.

Addressing Common Causes for TPMS Reading Incorrectly

Sometimes your TPMS may give an incorrect reading, showing either too high or too low tire pressure. This can be due to a faulty TPMS sensor, incorrect tire size, or a malfunctioning TPMS module.

To rectify, first, verify the tire pressure using a manual gauge. If the pressure is correct but the TPMS is reading incorrectly, inspect the sensors. They may be faulty or damaged, hence giving wrong readings. If the sensors are okay, check if the tires are of the correct size. Incorrect tire sizing can throw off the TPMS readings. Lastly, if the problem persists, have a professional inspect the TPMS module. The module might be malfunctioning and need repair or replacement.

Step-by-Step Guide to Resetting your TPMS Successfully

Resetting your TPMS can solve various errors, including the TPMS light not turning off or the system reading incorrectly. To reset, follow your vehicle’s manual instructions. It’s usually as simple as pressing a reset button on the dash and then driving the vehicle for a while for the system to recalibrate.

However, if the TPMS light comes on after resetting, it means the system has detected another problem. This could be low tire pressure or a malfunction in the TPMS. In such a case, troubleshoot as discussed in the previous sections.

Essential Preventative Measures to Avoid TPMS Errors

Regular inspection of the TPMS can help identify potential problems before they become serious issues. This includes checking the TPMS sensors for wear and tear, ensuring the sensor batteries are within their lifespan, and inspecting the TPMS module and antenna for damage or loose connections.

Also, always ensure your tires are properly inflated and of the correct size since these factors can affect the TPMS operation. Lastly, protect the TPMS from potential signal interference. Keep electronic devices that can interfere with the TPMS signal away from the vehicle.

Final Thoughts

Understanding and addressing the common TPMS errors is crucial for your vehicle’s safety and performance. Regular checks and maintenance of the TPMS components, coupled with proper tire inflation and sizing, can help avoid these errors. And if an error does occur, following the troubleshooting steps discussed can help resolve it effectively.


Why is my TPMS light on but tires are fine?
The TPMS light may be on due to a faulty sensor, a damaged antenna, or a communication malfunction within the system, not necessarily because of low tire pressure.

How long do TPMS sensor batteries last?
TPMS sensor batteries typically last between 5-10 years. Once they die, the entire sensor usually needs to be replaced.

Can signal interference cause TPMS errors?
Yes, devices transmitting at the same frequency as the TPMS or even other vehicles’ TPMS can interfere with the signal, causing errors.

Does tire size affect TPMS operation?
Yes, incorrect tire sizing can throw off the TPMS readings. Always ensure your tires are of the correct size as recommended by the vehicle’s manufacturer.

How do I reset my TPMS?
Follow your vehicle’s manual instructions to reset the TPMS. Usually, this involves pressing a reset button on the dash and then driving the vehicle for a while for the system to recalibrate.
