SA-9603-E Oxygen Sensor Remover/Installer

Warning: Refer to Battery Disconnect Warning in the Preface section.




1. Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
2. Disconnect the lower heated oxygen sensor connector.

Warning: In order to avoid being burned, do not service the exhaust system while it is still hot. Service the system when it is cool.

3. Remove the lower heated oxygen sensor from the exhaust front pipe.

Note: A special anti-seize compound is used on the oxygen sensor 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 serviced sensors will already have the compound applied to the threads. If a sensor is removed from any engine and is to be reinstalled, the threads must have an anti-seize compound applied before reinstallation.

1. Coat the threads of the oxygen sensor with anti-seize compound, if needed.

Caution: Refer to Fastener Caution in the Preface section.

2. Using SA-9603-E remover/installer , install the lower heated oxygen sensor to the exhaust front pipe and tighten to 50 N·m (37 lb ft).
3. Connect the lower heated oxygen sensor connector.
4. Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection.
