Oxygen Sensor: Service and Repair

NOTE The oxygen sensor has a permanently attached pig-tail and connector. This pig-tail should not be removed, since removal will affect proper operation of the oxygen sensor.

REMOVE/DISCONNECT
- Electrical connector from oxygen sensor.
- Using suitable wrench, carefully remove sensor from exhaust manifold or pipe. The oxygen sensor may be difficult to remove when engine temperature is below 120°F. Use caution, since excessive force may damage threads in exhaust manifold or pipe.

INSTALL/CONNECT
- If new sensor is being used, install sensor into manifold or pipe.
- If old sensor is being reused, coat threads with anti-seize compound, Part No. 5613695 or equivalent and install into manifold or pipe.
- Torque oxygen sensor to 41 N-m (30 lb. ft.), then reconnect electrical connector.
