Oxygen Sensor: Service and Repair
The oxygen sensor has a permanently attached wire and connector. This should not be removed, since the removal will affect proper operation of the
oxygen sensor.
1.
Disconnect electrical connector from oxygen sensor.
2.
Using a suitable oxygen sensor wrench, carefully remove the 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.
3.
If a new sensor is being used, install the new sensor into the manifold or pipe.
4.
If an old sensor is being reused, coat threads with anti-seize compound, then install the sensor into the manifold or pipe.
5.
Torque the oxygen sensor to specifications, then reconnect the electrical connector. Refer to SPECIFICATIONS/MECHANICAL for sensor
torque value.
