Tire Pressure Sensor Fault: What it means and how to fix it

You are driving your car, and suddenly the message “Tire Pressure Sensor Fault” appears on your dashboard. How much will this cost to repair? It will disappear if the tires have been inflated to the right pressure.

Tire pressure sensors are one of those modern car features that, when they work correctly, you don’t even know they’re there. But when they go wrong, it can be a real pain to figure out what’s going on. In this post, we’ll explain what a tire pressure sensor fault message is, and walk you through how to fix it. Keep reading for more information!

What does the “Tire Pressure Sensor Fault” mean?

The “Tire Pressure Sensor Fault” message indicates that there is an issue with the tire pressure monitoring system (TPMS). It is likely that there are issues with the connector or tire pressure sensor.

The error code may tell you that the tires’ air pressure is too low or too high or that one of the tire pressure sensors is defective.

You could have a bad TPMS controller unit or wiring. It is easiest to determine the cause by using an OBD2 scanner to examine your TPMS control units error codes.

Four Causes for the Tire Pressure Sensor Fault message

You may see the message "Tire pressure sensor fault" on your dashboards for one of several reasons. Be sure to check your trouble codes before you make any decisions. Below is a listing of 4 common reasons for a tire pressure sensor fault message.

1. Low Tire Pressure Sensor

This message is most often caused by a faulty tire pressure sensor. The batteries that power the tire pressure sensor are found in your tires. The batteries in the tires can eventually run out, so you will have to replace them all.

2. Tire pressure sensor lost memory

It can happen that both the tire pressure sensor and tire pressure controller lose contact with one another. Sometimes it is possible to reprogram the sensors in this situation. A TPMS reset tool is required to reprogram your sensors.

3. It was time to change your wheels

If you reside in a country that has cold weather you will probably need to switch between winter and summer tires. The TPMS needs to be reset following a wheel change. Also, if you don't have these tires you will need to program them. If the tire pressure sensor fault message appeared after the tire change – you might need to program the sensors.

4. Low tire pressure

Some car models have a tire pressure fault light that can indicate low tires pressure. Inflating your car is pretty easy, and if you do not know how to do it – you can go to any workshop or fuel station and let it do for you. Ensure that you have the exact tire pressure – as too high pressure can also cause this light to come on.

What does the TPMS system do?

Two different modes of operation can be used by a TPMS system. The TPMS system will be installed in vehicles manufactured after 2007. Some cars have sensors inside each tire. These sensors detect your tire pressure and transmit it to the TPMS control unit.

If the tire pressure is too high or too low or the control unit cannot communicate with your sensors, the message “Tire Pressure Sensor Fault” appears on your dashboard.

Others cars do not have any sensors, so they use ABS sensors to calculate wheel rotation. The wheel diameter that is compressed by low pressure means it must turn faster in order to maintain the same speed. The vehicle records any difference in speed between the wheels as an error code on your ABS or TPMS.

To determine the exact tire pressure, the car must be driven for some distance. It is a rough estimate and does not reflect the actual tire pressure.

How to fix the “Tire Pressure Sensor Fault” Message?

The tire pressure sensor can be fixed easily.

1. Check tire pressure

You should first make sure you have correct tire pressure. You can check your tire pressure using a tire pressure tester. Check the label on your tires to ensure you are getting the correct pressure. You can often find the label on the body behind the driver’s door. It can be found in the repair manual.

2. You can reset with the Tire Pressure button or with a scanner

After you've inflated the tires to the right pressure, it is often necessary to reset the system manually. You may have to drive around for 15 minutes before the light turns off in certain cars. To reset your vehicle's TPMS, refer to the manual. You may need to use a diagnostic tool for some vehicles.

3. Trouble codes?

You can still see the error code by reading the TPMS System error codes. This could indicate a problem with your tire pressure sensors, or that the sensor is damaged. Only the diagnostic scanner can diagnose this problem. You will require a scanner for reading enhanced trouble codes in your car to determine the TPMS controller module.

4. Reprogram Tire Pressure Sensors

The communication and programming values between the tire pressure sensors and the TPMS control system module can sometimes be lost by the sensor. You will need to reprogram the sensor to the control unit if this occurs. This is often done using a quality reset tool for TPMS.

5. Replacing the faulty pressure sensor for your tires

You may have a defective tire pressure sensor if you've tried all the possible solutions and still have problems. You should check the trouble codes for the sensor that is causing the problem and then replace it. After reprogramming the sensor, do not forget.

Is the pressure sensor for your tires located where?

Most tire pressure sensors can be found inside the tires of your car. It is usually visible when you examine the valve. A nut is often placed around the valve when a tire pressure sensor has been installed.

You can find out this information by either removing your tires or calling the manufacturer. authorized dealer You can ask.
