Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is off.
Tools Required: OBD-II scanner, tire pressure gauge, socket set, and a jack.

2. Inspect and Replace TPMS Sensors

Step 1: Remove the Tire
- Loosen the lug nuts using a socket wrench.
- Jack up the vehicle and secure it with jack stands.
- Remove the lug nuts and take off the tire.
Step 2: Access TPMS Sensor
- Locate the valve stem of the tire and remove the sensor by unscrewing it from the valve stem using a wrench.
Step 3: Replace with New Sensor
- Install the new TPMS sensor by screwing it onto the valve stem.
- Reattach the tire to the vehicle and hand-tighten the lug nuts.
Step 4: Lower the Vehicle
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Reset the TPMS System

Step 1: Turn the Ignition On
- Turn the ignition to the "On" position without starting the engine.
Step 2: Reset the TPMS
- Press the TPMS reset button (usually located under the steering wheel or in the glove compartment) until the TPMS light blinks three times.
Step 3: Start the Engine
- Start the engine and let it run for a few minutes to allow the system to recalibrate.
