If your tire pressure sensor is not working, start by checking the tire pressure manually and inflating the tires to the recommended levels. This quick fix ensures safety while you troubleshoot further.
Why Is My Tire Pressure Sensor Not Working?
Understanding why your tire pressure sensor might be malfunctioning is crucial. Common causes include:
- Dead battery: Tire pressure sensors often use small batteries that can deplete over time.
- Sensor damage: Physical damage from potholes or debris can impair sensor function.
- Signal interference: Electronic interference from other devices can disrupt sensor signals.
- Calibration issues: Sensors may require recalibration after tire changes or rotations.
How to Troubleshoot a Faulty Tire Pressure Sensor
1. Check Tire Pressure Manually
- Use a tire pressure gauge to measure each tire’s pressure.
- Inflate tires to the manufacturer’s recommended PSI, found on the driver’s side door jamb.
2. Inspect the Sensor for Damage
- Visually examine the valve stems for cracks or damage.
- Look for signs of corrosion or wear, which might indicate a need for replacement.
3. Reset the Tire Pressure Monitoring System (TPMS)
- Consult your vehicle’s manual for specific reset instructions.
- Typically, this involves pressing a reset button or using a menu option on the dashboard.
4. Replace the Sensor Battery
- If accessible, replace the sensor battery. This often requires professional assistance.
5. Seek Professional Help
- If issues persist, visit a mechanic or tire specialist for a thorough diagnostic and repair.

Common Questions About Tire Pressure Sensors
How Long Do Tire Pressure Sensors Last?
Tire pressure sensors typically last 5-10 years, depending on usage and environmental conditions. Regular maintenance and careful driving can extend their lifespan.
Can I Drive With a Faulty Tire Pressure Sensor?
While you can drive with a faulty sensor, it’s not recommended. A malfunctioning sensor means you won’t receive alerts about low tire pressure, increasing the risk of a blowout or reduced fuel efficiency.
How Much Does It Cost to Replace a Tire Pressure Sensor?
Replacing a tire pressure sensor can cost between $50 and $150 per sensor, depending on the type and brand. Labor costs may add to this expense.
What Are the Signs of a Failing Tire Pressure Sensor?
Signs include a persistent TPMS warning light, inaccurate pressure readings, or complete lack of alerts when tire pressure is low.
Do All Cars Have Tire Pressure Sensors?
Since 2008, all new vehicles in the U.S. are required to have tire pressure monitoring systems. Older vehicles may not have this feature unless retrofitted.
Next Steps
If your tire pressure sensor is not working, start by manually checking and adjusting tire pressure. If issues persist, consider consulting a professional to diagnose and repair the sensor.
