CAUTION: The Oxygen Sensor provides the Engine Control Module with information regarding the air/fuel mixture by transmitting a voltage signal through a permanently attached wire and connector. Removal of the wire and/or the connector from the sensor would greatly affect the performance and the exhaust emissions of the vehicle.
CAUTION: The Oxygen Sensor may be difficult to remove when engine temperature is below 120°F. DO NOT use excessive force. Damage to the threads or the sensor may result.
1. Disconnect harness connector from oxygen sensor.
DO NOT cut the electrical wire(s) if the sensor is going to be installed for use.
2. Using a suitable wrench or socket assembly, remove the sensor.
3. If a new sensor is being used, install the new sensor into the manifold or pipe.
4. If the old sensor is being reused, coat the sensor threads with anti-seize compound, then install the sensor into the manifold or pipe.
5. Torque the Oxygen Sensor to 40-50 N-m (30-36 ft lb).
6. Connect the electrical connector, and verify that the sensor is functioning normally.
