How to Reset TPMS Warning Light (Step-by-Step Guide)
If your TPMS warning light is on, it usually means your tyre pressure monitoring system has detected an issue. This could be low tyre pressure, a faulty TPMS sensor, or a system fault.
If you need help resetting your TPMS warning light, Fix My TPMS provides mobile TPMS services in London and Essex, including diagnostics, sensor replacement and programming.
In this guide, we explain how to reset the TPMS warning light safely, when it works, and when you may need professional TPMS diagnostics.
What Does the TPMS Warning Light Mean?
The TPMS, or Tyre Pressure Monitoring System, monitors the air pressure in your tyres. If the pressure drops too low, the system triggers a warning light on your dashboard.
Common causes include:
- Low tyre pressure
- Temperature changes affecting pressure
- Faulty TPMS sensor
- Dead sensor battery
- System needing recalibration
How to Reset TPMS Warning Light
1. Check and inflate your tyres
Before resetting anything, check all tyres using a pressure gauge. Inflate them to the manufacturer’s recommended PSI, usually found inside the driver’s door, fuel cap or vehicle manual.
2. Drive the vehicle
In many cases, driving for 10–20 minutes at a steady speed allows the system to automatically reset after the tyre pressures are corrected.
3. Use the TPMS reset button
Some vehicles have a TPMS reset button, often located under the steering wheel, in the glove box or near the dashboard controls.
- Turn the ignition on without starting the engine
- Press and hold the TPMS reset button
- Wait until the warning light blinks
- Start the engine and drive the vehicle
4. Use the vehicle menu settings
Many modern vehicles allow TPMS reset through the dashboard, infotainment screen or vehicle settings menu.
- Go to vehicle settings
- Select tyres, TPMS or tyre pressure
- Choose reset, relearn or calibration
- Drive the vehicle if required
Why Your TPMS Light Won’t Reset
If the TPMS warning light stays on after resetting, there may be an underlying fault. A reset will not fix a failed sensor or programming issue.
Common reasons include:
- Faulty TPMS sensor
- Sensor battery failure
- Incorrect sensor programming
- Damaged valve or corrosion
- Wrong tyre pressure set after replacement
When You Need TPMS Diagnostics
If your TPMS warning light will not reset, professional diagnostics are recommended. This helps identify whether the issue is low tyre pressure, a failed sensor, a programming fault or a communication issue.
At Fix My TPMS, we provide:
We use professional diagnostic equipment to identify the exact fault quickly and accurately across London and Essex.
TPMS Reset vs TPMS Repair
Resetting the TPMS light works when the issue is temporary, such as corrected tyre pressure or recalibration after tyre inflation.
However, if the system has a fault, you may need:
- TPMS sensor replacement
- TPMS programming
- System relearn
- Valve or component repair
Do All Vehicles Reset TPMS the Same Way?
No. TPMS reset procedures vary depending on the manufacturer and system type. Some vehicles reset automatically, while others require manual reset, dashboard calibration or specialist diagnostic equipment.
Some vehicles use:
- Direct TPMS, with sensors inside each wheel
- Indirect TPMS, using ABS and wheel speed data

Frequently Asked Questions
Can I drive with the TPMS light on?
You can drive with the TPMS light on for a short time, but it is not recommended. The light may indicate unsafe tyre pressure or a system fault that needs checking.
How long does it take to reset TPMS?
If the issue is pressure-related, the TPMS light may reset after 10–20 minutes of driving. If the light stays on, diagnostics may be needed.
Why does my TPMS light come back on?
If your TPMS light comes back on, there may be a slow puncture, incorrect tyre pressure, a faulty sensor or a programming issue.
Can a TPMS sensor stop the light from resetting?
Yes. If a TPMS sensor has failed or the battery is dead, the warning light may stay on until the sensor is replaced and programmed.
