Oxygen Sensor: Service and Repair
REMOVAL
NOTE: The Heated Oxygen Sensor (HO2S) and the Oxygen Sensor use a permanently attached pigtail and connector. Do not remove this pigtail from
the Heated Oxygen Sensor. Damage or the removal of the pigtail or the connector could affect the proper operation of the sensor.
Take care when handling the HO2S and the O2S. Keep the in-line electrical connector and the louvered end free of grease, dirt, or other contaminants.
Also avoid using cleaning solvents of any type. Do not drop the HO2S or the O2S. Do not roughly handle the HO2S or the O2S.
When the engine temperature is below 48 °C (120 °F), the Heated Oxygen Sensor (HO2S) may be difficult to remove. Excessive force may damage the
threads in the exhaust manifold or the exhaust pipe.
1. Turn OFF the ignition.
2. Raise the vehicle.
3. Remove the electrical connector.
NOTE: The use of excessive force may damage the threads in the exhaust pipe.
4. Carefully remove the rear heated oxygen sensor using J 39194 the HO2S Removal tool.
INSTALLATION
IMPORTANT: A special anti-seize compound is used on the Heated Oxygen Sensor (HO2S) threads. The compound consists of liquid graphite and
glass beads. The graphite tends to burn away, but the glass beads remain, making the sensor easier to remove. New, or service replacement sensors
already have the compound applied to the threads. If the sensor is removed from an engine and if for any reason it is to be reinstalled, the threads must
have anti-seize compound applied before the reinstallation.
