Important safety information - read before proceeding

•Ensure the vehicle is securely lifted and supported on jack stands before working on tires.
•Always wear safety glasses when working with tires and wheels to protect against debris.

Symptoms

•TPMS warning light illuminated on the dashboard
•Inaccurate tire pressure readings displayed
•Warning message indicating low tire pressure
•Difficulty resetting the TPMS after tire inflation or rotation
•Unusual tire wear patterns

Diagnostic Steps

1
Check tire pressures using a reliable tire pressure gauge to ensure they are within the manufacturer's recommended specifications.
2
Scan the vehicle’s OBD-II system for any TPMS-related error codes using an appropriate diagnostic scanner.
3
Inspect all tires visually for signs of damage, punctures, or wear that could affect pressure readings.
4
Verify the condition and operation of the TPMS sensors, ensuring they are not damaged or corroded.
5
Check the battery levels of the TPMS sensors, especially if the vehicle is equipped with direct TPMS.
6
Confirm that the TPMS system has been properly recalibrated after any tire changes or rotations.

Solution

Solution

1. Preparation

Gather tools and equipment: OBD-II scanner, tire pressure gauge, jack, jack stands, lug wrench, and possibly a TPMS reset tool.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Check and Adjust Tire Pressures

Remove the valve caps from each tire.
Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate each tire to the recommended pressure specified on the driver’s side door jamb.
Reinstall the valve caps securely.

3. Reset the TPMS

Turn the ignition to the "ON" position without starting the engine.
Locate the TPMS reset button (usually found under the steering wheel or on the dashboard).
Press and hold the TPMS reset button until the TPMS warning light blinks three times.
Release the button and wait for the light to turn off.

4. Recalibrate the System (if necessary)

If the TPMS does not reset, use an OBD-II scanner to access the TPMS module.
Follow the scanner's prompts to recalibrate or relearn the TPMS sensors.
Confirm that the system acknowledges the changes and check for any error codes.

5. Replace Faulty Sensors (if necessary)

If sensor malfunction is confirmed, raise the vehicle using a jack and secure it with jack stands.
Remove the tire from the wheel using a lug wrench.
Detach the faulty TPMS sensor from the rim and replace it with a new one.
Reinstall the tire and wheel, and ensure lug nuts are tightened to the manufacturer’s torque specifications.
