Understanding Your TPMS
Before diving into troubleshooting, it’s important to understand how the TPMS works. There are two main types: direct and indirect. Direct TPMS uses sensors within each tire to measure pressure and transmit data wirelessly to the car’s computer. Indirect TPMS, on the other hand, monitors tire pressure by measuring wheel speed using the ABS system. If a tire is low, it will rotate at a different speed than the others, triggering the warning light. Knowing which system your vehicle utilizes is the first step to accurate diagnosis.
Checking Tire Pressure with Gauge
Common TPMS Problems and Solutions
Low Tire Pressure
The most obvious cause of a TPMS warning light is, of course, low tire pressure. Check your tire pressure using a reliable gauge and inflate to the recommended PSI listed in your owner’s manual or on the sticker inside the driver’s side doorjamb.

Sometimes, it can take a few miles of driving for the system to recognize the change.
Dead Battery in TPMS Sensor
Like any battery-powered device, TPMS sensors have a limited lifespan. After several years, the internal battery can die, causing the sensor to stop transmitting data. This is a common problem, especially in older vehicles. Replacing the sensor is usually the only solution. While some may attempt to replace the battery within the sensor, this is often more complex and less reliable than simply replacing the entire unit.
“A dead TPMS sensor battery is one of the most frequent issues we see,” says John Miller, Certified Automotive Technician at Miller’s Auto Repair. “It’s a simple fix, but important for maintaining proper tire pressure monitoring.”
Damaged Sensor
Physical damage to a sensor, such as from hitting a curb or pothole, can also cause it to malfunction. Similarly, corrosion on the sensor can interfere with its operation. A visual inspection of the sensor can often reveal such damage. If a sensor appears damaged, it will need to be replaced.
Faulty TPMS Module
While less common, the TPMS module itself can fail. This module receives signals from the sensors and triggers the warning light. Diagnosing a faulty module requires specialized diagnostic tools, and replacement is best left to a professional. If you’ve ruled out all other possibilities, this might be the culprit.
Resetting the TPMS
After fixing the underlying issue, sometimes you need to reset the TPMS. The process varies depending on the vehicle, so consult your owner’s manual for specific instructions. Some vehicles have a reset button or procedure, while others will reset automatically after driving a certain distance.
How to Fix Car Tire Pressure Sensor: A Quick Recap
If you’re facing a TPMS issue, here’s a simplified breakdown of how to fix it:
- Check tire pressure: Inflate tires to the recommended PSI.
- Inspect sensors: Look for visible damage or corrosion.
- Consider sensor battery life: If the sensors are old, they might need replacing.
- Consult a professional: If you suspect a faulty module, seek expert help.
- Reset the TPMS: Follow your vehicle’s specific reset procedure.
