Solution

1. Preparation

Gather necessary tools: OBD-II scanner, TPMS tool, tire pressure gauge, socket set.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace TPMS Sensors

Sub-steps:
1. Remove the tire from the vehicle using a jack and jack stands.
2. Use a tire iron to loosen and remove the lug nuts and take the tire off.
3. Locate the TPMS sensor mounted on the valve stem inside the tire.
4. If the sensor is damaged or the battery is dead, replace it with a new sensor compatible with the Cayenne E3.
  - Tools Required: TPMS sensor removal tool, new TPMS sensor.
5. Install the new sensor and ensure it is properly secured to the valve stem.
6. Reinstall the tire onto the wheel hub, tighten lug nuts to the manufacturer’s specified torque settings (typically around 90-120 Nm).

3. Recalibrate the TPMS

Sub-steps:
1. Inflate all tires to the recommended pressure as indicated on the driver’s door jamb sticker.
2. Use the TPMS tool to initiate a sensor relearn procedure, or follow the vehicle’s manual to reset the TPMS.
3. Confirm that the system recognizes the new sensor and that the warning light is off.
