•Allow tires to cool before measuring pressures or performing repairs.

Symptoms

•TPMS warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed
•Warning messages on the vehicle's multi-information display
•Tire pressure readings fluctuating unexpectedly
•Vehicle handling issues (e.g., pulling to one side)

Diagnostic Steps

1
Check the current tire pressures using a reliable tire pressure gauge.
2
Use an OBD-II scanner to check for any TPMS-related error codes.
3
Inspect each tire for visible damage or punctures.
4
Verify that the TPMS sensors are functioning by using a TPMS tool to read sensor data.
5
Examine the TPMS fuse to ensure it is not blown.
6
Check for any signs of moisture or corrosion in the TPMS connectors.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather necessary tools including an OBD-II scanner, tire pressure gauge, and TPMS tool.
Ensure the vehicle is parked on a level surface and that the tires are cool.
Disconnect the battery for safety if necessary.

2. Check and Adjust Tire Pressures

Remove the valve caps from each tire.
Use the tire pressure gauge to measure the tire pressure of each tire.
Compare readings to the recommended tire pressures listed on the driver’s side door jamb.
Inflate or deflate tires as needed to match the recommended pressure.
Reinstall valve caps securely.

3. Reset the TPMS

Turn the ignition key to the "ON" position without starting the engine.
Locate the TPMS reset button (usually under the steering wheel or on the dashboard).
Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
Start the engine and allow the vehicle to run for a few minutes to complete the reset.

4. Replace TPMS Sensors (if necessary)

If the sensors are faulty, lift the vehicle and remove the tire from the wheel.
Use a tire mounting machine to demount the tire.
Replace the TPMS sensor with a new one, ensuring it is compatible with the vehicle.
Reassemble the tire and wheel, re-mounting it on the vehicle.
Repeat the reset procedure to ensure the new sensor is recognized by the system.
