How can I fix TPMS?
If your vehicle's Tire Pressure Monitoring System (TPMS) is malfunctioning, there are several steps you can take to diagnose and fix the problem. TPMS is an important safety feature that alerts drivers when one or more tires have significantly low air pressure, which can be dangerous. In this article, we'll provide a detailed guide on how to troubleshoot and resolve common TPMS issues.
What is TPMS and How Does it Work?
TPMS is a system installed in most modern vehicles that continuously monitors the air pressure in each tire. It uses sensors located in the wheels to detect when a tire's pressure drops below a certain threshold, typically around 25% below the recommended PSI. When this happens, the TPMS warning light on the dashboard illuminates, alerting the driver to check and inflate the affected tire(s).
Common TPMS Issues and How to Fix Them
There are several common problems that can cause TPMS malfunctions. Here are the most frequent issues and how to address them:
1. TPMS Warning Light is On
- Check Tire Pressure: The first step is to check the air pressure in all four tires and inflate them to the recommended PSI listed in your vehicle's owner's manual or on the driver's side door jamb sticker.
- Inspect TPMS Sensors: If the warning light remains on after inflating the tires, the issue may be with one or more of the TPMS sensors. Visually inspect the sensors for any damage or corrosion, and replace any faulty sensors.
- Reset the TPMS System: After addressing any sensor issues, you'll need to reset the TPMS system. This is typically done by following the reset procedure outlined in your owner's manual, which often involves driving the vehicle at a certain speed for a set distance.
If the warning light remains on after these steps, there may be a more complex issue with the TPMS system that requires professional diagnosis and repair.
2. TPMS Warning Light Flashes
If the TPMS warning light is flashing, it typically indicates a system malfunction. This could be caused by a faulty sensor, a problem with the TPMS control module, or interference with the TPMS signal. In this case, you'll need to have the system diagnosed and repaired by a qualified mechanic.
3. TPMS Sensor Battery Replacement
TPMS sensors are powered by small batteries that typically last 5-10 years. If the TPMS warning light is on and you've ruled out other issues, the sensor battery may need to be replaced. This is a relatively simple process that can be done by a mechanic or even by the vehicle owner in some cases.
Conclusion
Addressing TPMS issues is important for maintaining the safety and performance of your vehicle. By following the steps outlined in this guide, you can diagnose and resolve common TPMS problems, ensuring your tires are properly inflated and your vehicle is operating safely. If you encounter any persistent or complex TPMS issues, it's best to have your vehicle inspected and repaired by a qualified automotive technician.
Can a TPMS sensor be fixed?
Signs of TPMS failure include dashboard warning lights, inaccurate tire pressure readings, inability to reset the TPMS warning light, and an unresponsive TPMS system. Steps to fix a bad TPMS sensor include checking the battery voltage, reprogramming or resetting the sensor, and replacing the sensor if necessary.
How to fix TPMS issue?
If the light remains on after adjusting the tire to the proper PSI, you may need to repair your tire, have your TPMS inspected, or try one of the following: Go for a 10-minute drive. Get up to 50 MPH, if possible. Your vehicle may be equipped with a TPMS reset button or reset procedure in your vehicle control center.
How do I get the TPMS light to go off?
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.
How much does it cost to fix a TPMS?
The average cost to replace the TPMS Sensor is between $314 and $368. Find out TPMS Sensor replacement pricing for your vehicle.
