How to Fix Tire Sensor Fault

Have you ever been driving along when suddenly your tire pressure warning light comes on, accompanied by an alert stating “tire sensor fault”? It’s an unsettling feeling not knowing whether your tires are properly inflated or if there is actually something wrong with the tire pressure monitoring system (TPMS).

How to Fix Tire Sensor Fault

When this warning pops up, most vehicle owners aren’t quite sure what the root cause could be or how to resolve it.

In this blog post on how to fix tire sensor fault, I will walk through the most common reasons why your car might display a tire sensor fault message, and provide steps you can take to diagnose and potentially fix the issue.

By understanding what may be triggering the warning and learning some simple checks and repairs, you can save yourself a trip to the mechanic and get back to enjoying comfortable and safe drives.

Needed Tools

Before getting started, you will need a few tools to help diagnose and potentially fix the tire sensor fault. These include:

A Tire Pressure Gauge:

This will be used to manually measure the pressure in each tire.

An Air Compressor:

If your tires are underinflated, you may need an air compressor to pump them back up. Some gas stations have these available for public use, or you can purchase one for your own personal use.

A TPMS Reset Tool:

This is required to reset the system after any repairs have been made.

10 Simple Step-by-step Guides on How to Fix Tire Sensor Fault

Step 1: Check Tire Pressure

The first thing you should do when encountering a tire sensor fault is manually check the pressure in each tire using a tire pressure gauge. Compare the readings to what is recommended in your vehicle’s owner manual or on the sticker usually located on the driver’s side door jam.

A Tire Sensor Fault is Manually Check the Pressure

You may also want to check for any visible signs of tire damage such as punctures or cuts. It’s important to note that a significant difference in pressure between tires could indicate a leak or other issue.

Step 2: Inflate Tires

If the tire pressure is low, use an air compressor to fill your tires to the recommended levels. Be sure to check the pressure again after inflating to ensure it is within the recommended range. It is important to note that overinflated tires can also trigger a tire sensor fault, so be careful not to overdo it.

You can always let some air out if necessary. This step alone may resolve the issue. It is recommended to check your tire pressure at least once a month to ensure proper inflation.

Step 3: Look for Corroded Valve Stems

Valve stems are the small posts that you screw your tire gauge onto when checking tire pressure. These can corrode over time, causing air to leak out and triggering a tire sensor fault. If you see any signs of corrosion, it is best to replace them.

The new valve stems can be purchased at any auto parts store and are relatively inexpensive. You can also ask a mechanic to replace them for you if you are uncomfortable doing it yourself.

Step 4: Check the Batteries

Batteries Can Die and Need to Be Replaced

Each tire sensor has its own battery that powers it. Over time, these batteries can die and need to be replaced. If you have been noticing a persistent tire sensor fault warning, it may be due to a dead battery in one or more of your sensors.

You will need to purchase new batteries and replace them in the affected sensors. The batteries can be found at most auto parts stores and are relatively easy to replace.

Step 5: Reset the TPMS

If you have made any repairs or replaced a battery, you will need to reset the TPMS using a TPMS reset tool. This can be purchased at an auto parts store or online. Follow the instructions provided with the tool to reset the system. It is important to note that some vehicles may require a specific sequence of steps to reset the TPMS, so be sure to consult your owner’s manual.

Step 6: Check for Loose or Damaged Wires

In rare cases, a tire sensor fault warning may be caused by loose or damaged wires. If you have the tools and skills, you can check the wiring connections to ensure they are secure and not damaged. If you are not comfortable with this step, it is best to take your vehicle to a mechanic for a professional check. You do not want to accidentally cause more damage.

Step 7: Look for Faulty Sensors

If none of the previous steps have resolved the issue, it is possible that one or more of your sensors may be faulty. This can happen over time due to wear and tear or other factors. In this case, it is best to take your vehicle to a mechanic for a professional diagnosis. It is important to replace any faulty sensors as soon as possible to ensure the accuracy of your tire pressure readings.

Step 8: Consult your Vehicle’s Manual

If you are unsure about any of the previous steps or if they have not resolved the issue, consult your vehicle’s manual for specific troubleshooting tips and instructions. Different vehicles may have slightly different procedures for diagnosing and fixing a tire sensor fault, so it is important to refer to your manual. The manual may also have information on any known issues or recalls related to the TPMS in your vehicle.

Step 9: Take Your Vehicle to a Mechanic

Still Unable to Resolve the Tire Sensor Fault

If you are still unable to resolve the tire sensor fault, or if you do not have the tools or skills required for some of the previous steps, it may be best to take your vehicle to a mechanic for a professional diagnosis and repair. They will have the necessary tools and expertise to identify and fix any issues with your TPMS.

Step 10: Consider Replacing All Sensors

If you have been experiencing recurring tire sensor faults, it may be worth considering replacing all of your sensors at once. This can help prevent future issues and give you peace of mind knowing that all of your sensors are in good working condition.

Consult with a mechanic for the best options and pricing for new sensors. But keep in mind, that this step may not be necessary for everyone and should only be considered after trying the previous steps.

Following these simple steps on how to fix tire sensor fault can help you diagnose and potentially fix a tire sensor fault. It is important to address this issue promptly as it can affect the accuracy of your tire pressure readings and compromise your safety on the road. By understanding how to fix a tire sensor fault, you can save time and money in the long run, while also ensuring safe and comfortable drives.
