Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the engine.
Ensure safety equipment is available (gloves, goggles).

2. Inspect TPMS Sensors

Tools Required: Tire pressure gauge, OBD-II scanner, socket set.
Remove the valve caps from each tire.
Use the tire pressure gauge to check each tire's pressure against the manufacturer's specifications.
If any tire is low, inflate to the correct pressure.
Check the TPMS sensors for any visible damage or corrosion.

3. Replace Faulty TPMS Sensors

Tools Required: Torque wrench, socket set, valve core tool.
If a TPMS sensor is found to be faulty:
1. Remove the tire from the wheel using a tire machine.
2. Unscrew the old sensor from the valve stem using the socket set.
3. Install the new sensor and tighten to the manufacturer’s torque specifications (usually around 4-5 Nm).
4. Re-mount the tire and balance it if necessary.

4. Reset TPMS System

Tools Required: OBD-II scanner.
With the vehicle in the on position (engine off), connect the OBD-II scanner.
Navigate to the TPMS reset function and follow the on-screen instructions to reset the system.
If the vehicle has a manual reset procedure, follow the manufacturer’s guidelines.
