What Does Tire Pressure Sensor Fault Mean

Tire pressure sensor fault is a diagnostic trouble code (DTC) that indicates malfunctioning of the tire pressure monitoring system (TPMS). When this code appears, it means that an incorrect or invalid signal has been detected by the TPMS. This can occur due to a faulty wheel speed sensors, low battery power in either the TPMS receiver or transmitter unit, poor connection between the two components, faulty TPMS module and/or incorrect tire pressure readings.

The most common causes are low or incorrectly inflated tires and/or damaged or corroded wiring harnesses. It is important to immediately fix any issue causing this error as it could lead to uneven wear on your tires and reduced fuel economy if left unresolved.

If you see a tire pressure sensor fault warning light illuminated on your dashboard, it means that one or more of your tires is not at the proper pressure. This can be caused by anything from low air pressure in the tires to a malfunctioning tire pressure monitoring system (TPMS). The most important thing to do if you notice this warning light is to check all four of your tires and ensure they are properly inflated according to the manufacturer’s recommended levels.

If any of the tires need additional air, refill them as soon as possible, then reset the TPMS using your car’s onboard computer or user manual instructions.

How Do I Fix Tire Pressure Sensor Fault?

If you are experiencing a tire pressure sensor fault, it is important to determine the cause of the problem. There are several potential causes for this issue, including low air pressure in your tires, faulty sensors or wiring, and worn out valves. If you find that your tires have low air pressure and this is causing the sensor fault, then simply fill them back up to their recommended level with an air compressor or at a local service station.

If the sensors themselves are faulty or if there is some kind of wiring problem then you may need to replace either individual components or all four sensors depending on which ones are not working correctly. Finally, if your valves have become worn out due to age or other factors then they should be replaced as soon as possible in order to ensure proper operation of the tire pressure monitoring system and avoid further damage down the road.

Can You Drive With Tire Sensor Fault?

Driving with a tire sensor fault can be a very dangerous situation, as it may cause significant damage to your vehicle and create potentially hazardous driving conditions. Tire sensors are designed to monitor the air pressure in each of your car’s tires, alerting you when they become too low or too high. When this warning light comes on, it means one or more of the tires is not properly inflated which can lead to poor handling, increased fuel consumption and uneven wear on the treads.

Driving with such an issue can also increase braking distance so it is important that you take action immediately by either checking and adjusting the tire pressures yourself or visiting a mechanic for assistance. It is illegal in many states and provinces to drive with a tire sensor fault so always check beforehand if possible before taking any risks!

What Causes a Tire Pressure Sensor Fault?

There are many potential causes of a tire pressure sensor fault. The most common is when the valve stem on the wheel becomes loose or corroded, which can cause a loss of connection between the sensor and wheel. Another possible issue is if any part of the tire pressure monitoring system has failed due to age or corrosion, such as the sensors themselves, wiring harnesses, control modules, or antennas.

It’s also important to check for dirt buildup around sensors and valves that may be preventing an accurate reading from being taken. Other causes include improper installation of replacement tires/wheels (such as incorrect size), damage done by road debris (potholes/stones), low battery power in TPMS units, and faulty components in general. Regardless of what might be causing your specific tire pressure sensor fault, it’s important to have it checked out right away before more serious issues arise – driving with underinflated tires can lead to premature wear on both your vehicle’s suspension and brakes!

How Serious is a Tire Pressure Sensor Fault?

A tire pressure sensor fault is a serious issue that should not be ignored. When the sensor fails, it can cause the vehicle’s computer to misread or misinterpret tire pressures and lead to an unsafe driving situation. Additionally, it can reduce fuel efficiency as well as affect how your car handles on the road.

On top of this, without proper maintenance and repair when necessary, a faulty tire pressure sensor could eventually cause irreparable damage to your tires and wheels. It’s important then to pay attention to any warning signs your car may be exhibiting such as illuminated dashboard lights or if you notice that one side of your vehicle is handling differently than the other side while driving. If either of these scenarios occur, make sure you have it checked out by a qualified mechanic right away so they can diagnose and repair any issues with the tire pressure sensors before further damage occurs.

Is It Safe to Drive With Tire Pressure Sensor Fault

Driving with a tire pressure sensor fault is not recommended, as it can present a risk to the driver, passengers and other road users. Tire pressure sensors are designed to alert you when your tires have low air pressure or an issue with their tread depth. If there is a fault in the system, it could fail to warn you of potential dangers such as underinflated tires which can lead to premature wear on the tire and pose an increased risk of blowouts or loss of control due to poor grip on the road surface.

Therefore, it’s important that any issues with your tire pressure sensor should be addressed promptly by an experienced mechanic.

How to Fix Your Tire Pressure Sensor Fault?

If your vehicle’s tire pressure monitoring system (TPMS) is flagging a fault, the first step you should take is to check each of your tires for proper inflation. If any of them are significantly under-inflated, fill them up with air until they reach their recommended level. Then reset the TPMS and drive for about 10 minutes to see if that solved the problem.

If it didn’t, then you may need to have the sensor replaced by a professional mechanic or order a new one online and install it yourself.

Tire Pressure Sensor Fault Reset

A tire pressure sensor fault reset is a process used to clear any warnings related to the tire pressure monitoring system (TPMS) in your car. This can be done by using a scan tool that connects to your vehicle’s OBD-II port and allows you to read diagnostic trouble codes as well as resetting them. The procedure typically involves connecting the scan tool, checking for any stored codes, and then clearing them.

After this is complete, the TPMS should be functioning normally again.


The Tire Pressure Sensor Fault is a common issue that can occur in many makes and models of vehicles. It’s important to be aware of this issue so you can diagnose and repair it quickly, as an incorrect tire pressure reading can lead to major safety issues. The best way to prevent this fault from occurring is by regularly checking your tire pressure levels and ensuring they are kept at the recommended levels for your vehicle.

Taking proper care of your tires will help keep you safe on the roads and reduce the chances of encountering any significant problems with your vehicle’s tire pressure sensors.
