Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Safety gear (gloves, safety glasses) should be worn.

2. Inspect and Replace TPMS Sensors

Remove Tires:
- Loosen lug nuts with a socket set.
- Use a jack to lift the vehicle and secure with jack stands.
- Remove the tires from the wheel hub.
Remove TPMS Sensors:
- Carefully deflate the tire if necessary.
- Use a tire iron to remove the valve stem nut and detach the TPMS sensor from the wheel.
Inspect Sensors:
- Check for any signs of damage or corrosion; replace if necessary.
Install New Sensors (if needed):
- Attach the new TPMS sensor to the valve stem and secure with the nut.
Reinstall Tires:
- Place the tire back onto the wheel hub.
- Tighten lug nuts to the manufacturer’s specified torque value.

3. Reset TPMS

Turn on Ignition:
- Without starting the engine, turn the ignition key to the "ON" position.
Reset TPMS:
- Use the TPMS reset button (usually located beneath the steering column) to reset the system.
- Alternatively, follow the vehicle's owner’s manual for specific reset instructions.
