Oxygen Sensor: Service and Repair
CAUTION: The oxygen sensor has a permanently attached wire and connector. This should not be removed, as removal will affect engine performance
and emissions.
1.
Disconnect oxygen sensor electrical connector.
2.
Using a suitable tool, carefully remove the sensor from exhaust manifold or pipe. The oxygen sensor may be easier to remove when engine
temperature is above 120°F.
CAUTION: Excessive force may damage threads in exhaust manifold or pipe.
3.
If a new sensor is being used, verify that the threads are coated with anti-seize compound, then install the new sensor in the manifold or pipe.
4.
If a used sensor is being used, coat sensor threads with a nickel based anti-seize compound, then install the sensor into the manifold or pipe. Do
not use graphite or other anti-seize compounds.
5.
Torque the oxygen sensor to specifications, then connect the electrical connector. Refer to MECHANICAL SPECIFICATIONS for sensor
torque value.
