Oxygen Sensor (02S 1)

REMOVAL PROCEDURE




1. Disconnect the negative battery cable.

NOTE: The oxygen sensor (O2S 1) uses a permanently attached pigtail and connector. This pigtail should not be removed from the O2S 1. Damage or removal of the pigtail or the connector could affect proper operation of the O2S 1. Take care when handling the O2S 1. Do not drop or damage the O2S 1.

2. Disconnect the O2S 1 connector.

NOTE: The oxygen sensor may be difficult to remove when the engine temperature is below 48 °C (118 °F). Excessive force may damage the threads in the exhaust manifold.

3. Carefully remove the O2S 1 from the exhaust manifold.

INSTALLATION PROCEDURE

IMPORTANT: A special anti-seize compound is used on the O2S 1 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.




1. Coat the threads of the O2S 1 with an anti-seize compound, if needed.
2. Install the O2S1 into the exhaust manifold.

Tighten
Tighten the oxygen sensor sensor to 41 Nm (30 lb-ft).

3. Connect the O2S1 connector.
4. Connect the negative battery cable.
