- Locate the existing sensor, unscrew it from the exhaust pipe, and carefully disconnect the wiring connector.
- Install the new sensor, ensuring the cable is routed correctly to the 540 mm length specified.
- Reconnect the wiring and clear any diagnostic trouble codes (DTCs) from the vehicle ECU.
Care:
Do not handle the sensor tip with bare hands or expose it to chemicals, as debris or oils can interfere with thermal readings.
