Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the vehicle battery to avoid electrical shorts.

2. Replace Faulty TPMS Sensors

Remove the Wheel:
- Loosen lug nuts using a socket set.
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the wheel.
Access and Replace the Sensor:
- Remove the tire from the rim using a tire machine or manual tire-changing tools if necessary.
- Locate the TPMS sensor attached to the valve stem.
- Disconnect the sensor from the valve stem and remove it.
- Install the new TPMS sensor by attaching it to the valve stem and securing it properly.
- Reinstall the tire onto the rim and balance it if needed.

3. Reset the TPMS

Reinstall the Wheel:
- Place the wheel back on the hub and hand-tighten lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Reconnect Battery:
- Reconnect the battery terminals ensuring proper polarity.
Reset the TPMS System:
- Turn on the ignition without starting the engine.
- Press and hold the TPMS reset button (usually located near the driver's side dashboard) until the TPMS light blinks three times.
- Start the engine and check if the TPMS light turns off.
