Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety warning: Disconnect the battery to prevent accidental electrical shorts.

2. Inspect and Replace Tire Pressure Sensors

Remove Tire from Rim:
- Loosen lug nuts with a socket set.
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel completely.
Access Tire Pressure Sensor:
- Deflate the tire completely.
- Use a tire bead breaker to separate the tire bead from the rim.
- Remove the tire from the rim using tire levers.
Remove Old Sensor:
- Locate the valve stem where the sensor is mounted.
- Unscrew the sensor from the valve stem and disconnect any wiring if applicable.
Install New Sensor:
- Install the new tire pressure sensor onto the valve stem.
- Ensure it is tightly secured and reconnect any wiring as needed.
Reassemble Tire:
- Refit the tire onto the rim and ensure the bead is properly seated.
- Inflate the tire to the manufacturer's recommended pressure.
Reinstall Wheel:
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle and use a torque wrench to tighten lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Reset TPMS

Reconnect Battery:
- Reconnect the battery and ensure all connections are secure.
Program New Sensors:
- Use the car's onboard menu to reset the TPMS. This may involve navigating through settings to find the TPMS reset option.
- Alternatively, use a TPMS tool to program the new sensors if necessary.
