How To Reset Tire Pressure Sensor Fault
If you’re experiencing a “TPMS Wheel Sensor Missing” error on your Mercedes-Benz, it indicates an issue with the Tire Pressure Monitoring System (TPMS). Here’s a step-by-step guide on how to reset the tire pressure sensor fault and potentially fix the problem:
Step 1: Check Tire Pressure
- Check All Tires: Use a tire pressure gauge to check the pressure of all four tires, including the spare if your vehicle monitors it.
- Inflate Tires: Inflate the tires to the recommended pressure level, which can usually be found on the sticker inside the driver’s door frame or in the owner’s manual.
Step 2: Drive the Vehicle
- Drive for 10-15 Minutes: After adjusting the tire pressures, drive the vehicle at a speed above 20 mph for about 10-15 minutes. This allows the TPMS to recalibrate and reset itself.
Step 3: Reset TPMS from the Dashboard
- Turn on the Ignition: Without starting the engine, turn the ignition key to the “On” position (or press the “Start” button once without pressing the brake).
- Access the TPMS Menu: Navigate through the dashboard menu using the steering wheel controls or the buttons on the instrument cluster to find the TPMS settings.
- Select ‘Reset’ or ‘Relearn’: Select the option to reset or relearn the TPMS. This might be labeled differently depending on the model year and system version.
- Confirm the Reset: Follow the prompts to confirm the reset.
Step 4: Verify Sensor Functionality
- Wait for a Few Minutes: After resetting the system, wait for a few minutes to see if the warning light turns off.
- Recheck Tire Pressure: If the warning light remains on, recheck the tire pressures to ensure they are correct.
Step 5: Inspect TPMS Sensors
- Check for Damage: Inspect the valve stems for any signs of damage or corrosion.
- Check Sensor Batteries: TPMS sensors have batteries that typically last 5-10 years. If your vehicle is older, the batteries might need replacement.
