Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the ignition is turned off.
• Disconnect the vehicle battery for safety.

2. Inspect and Replace TPMS Sensor

1. Remove Wheel:

   • Loosen lug nuts with a socket wrench.
   • Lift the vehicle using a jack and secure it with jack stands.
   • Remove the wheel to access the TPMS sensor.

2. Check Sensor:

   • Locate the TPMS sensor mounted on the valve stem.
   • Remove the sensor by unscrewing it from the valve stem using a wrench.
   • Inspect the sensor for damage or corrosion.

3. Replace Sensor (if defective):

   • Install a new TPMS sensor by threading it onto the valve stem.
   • Tighten it to the manufacturer's specified torque (usually around 3-5 Nm).

4. Reinstall Wheel:

   • Place the wheel back on the hub.
   • Hand-tighten the lug nuts, then lower the vehicle.
   • Torque the lug nuts to the manufacturer’s specifications (typically around 100-120 Nm).

3. Reprogram the TPMS

1. Reconnect Battery:

   • Reconnect the vehicle battery and ensure all connections are secure.

2. Reprogram Sensors:

   • Follow the vehicle manufacturer's procedure to reprogram the TPMS sensors, which typically involves using a TPMS tool or the vehicle's onboard settings.
