Removal Procedure
WARNING:
Refer to Exhaust Service Warning .
CAUTION:
The oxygen sensor may be difficult to remove when the engine temperature is below 48°C (120°F). Excessive force may damage threads in the exhaust manifold or the exhaust pipe.
CAUTION:
Handle the oxygen sensors carefully in order to prevent damage to the component. Keep the electrical connector and the exhaust inlet end free of contaminants. Do not use cleaning solvents on the sensor. Do not drop or mishandle the sensor.
CAUTION:
A special anti-seize compound is used on the oxygen sensor threads. New service sensors should already have the compound applied to the threads. Coat the threads of a reused sensor with anti-seize compound P/N 5613695 or equivalent.
- Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection .
- Disconnect the heated oxygen sensor electrical connector.
- Unclip the heated oxygen sensor wiring harness clip from the turbocharger wastegate actuator vacuum control solenoid valve splash shield bracket.
- Remove the heated oxygen sensor (1) from the catalytic converter, use the CH-6129 remover.
