Solution

1. Preparation

Gather required tools and parts; ensure the vehicle is parked on a level surface.
Tools Required: Tire pressure gauge, OBD-II scanner, TPMS reset tool (if needed).
Safety Warnings: Ensure the vehicle is safely parked with the engine off before beginning work.

2. Adjust Tire Pressures

a. Remove the valve cap from each tire.
b. Use the tire pressure gauge to check the current pressure.
c. Inflate each tire to the recommended pressure specified in the owner’s manual or on the driver’s door jamb.
d. Replace the valve caps securely after checking the tire pressures.

3. Reset TPMS

a. Locate the TPMS reset button (usually found under the steering column or in the glove box).
b. With the vehicle in the "ON" position but the engine off, press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
c. Start the engine and allow the vehicle to run for a few minutes to complete the reset process.

4. Replace Faulty Sensors (if needed)

a. Remove the wheel from the vehicle using a jack and socket set.
b. Unscrew the valve stem nut to remove the TPMS sensor from the tire.
c. Install the new TPMS sensor and secure it with the valve stem nut, torquing to manufacturer specifications.
d. Reinstall the wheel and torque the lug nuts to the specified value.
