Removal Procedure
- Disconnect the negative battery cable.
- Disconnect the oxygen sensor (O2S) wiring harness connector.
- Remove the O2S from the pup converter.
Warning: Refer to Battery Disconnect Warning in the Preface section.
Caution: Refer to Heated Oxygen and Oxygen Sensor Caution in the Preface section.
Caution: Refer to Heated Oxygen Sensor Wire Repair Caution in the Preface section.
Caution: Remove oxygen sensors with the engine temperature above 48°C (120°F). Otherwise the oxygen sensors may be difficult to remove.
Installation Procedure
- Coat the threads of the oxygen sensor with an anti-seize compound, if needed.
- Install the oxygen sensor (O2S) and tighten to 39 N·m (29 lb ft).
- Connect the O2S wiring harness connector.
- Connect the negative battery cable.
Note: A special anti-seize compound is used on the O2S threads. This compound consists of a liquid graphite and glass beads. The graphite will burn away, but the glass beads will remain, making the sensor easier to remove. New or service sensors will already have the compound applied to the threads. If a sensor is removed from any engine and if for any reason it is to be reinstalled, the threads must have anti-seize compound applied before reinstallation.
Caution: Refer to Fastener Caution in the Preface section.
