Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Gather safety equipment such as gloves and safety glasses.

2. Reset TPMS

Step 1: Locate the TPMS reset button, usually found under the steering wheel or in the glove compartment.
Step 2: Turn the ignition to the "On" position without starting the engine.
Step 3: Press and hold the TPMS reset button until the tire pressure light blinks three times, then release the button.
Step 4: Drive the vehicle for 10-15 minutes at a speed of 50 mph or more to allow the system to recalibrate.

3. Replace TPMS Sensors (if faulty)

Step 1: Raise the vehicle using a jack and secure it with jack stands.
Step 2: Remove the wheel where the faulty TPMS sensor is located (use a tire iron to loosen lug nuts).
Step 3: Deflate the tire completely and break the bead using a tire changer or manual method.
Step 4: Remove the TPMS sensor from the tire valve and replace it with a new sensor.
Step 5: Reassemble the tire and wheel, ensuring proper seating of the tire bead.
Step 6: Inflate the tire to the recommended pressure and remount the wheel to the vehicle.
