OXYGEN SENSOR
Removal and Installation Procedure
1. Disconnect the negative battery cable.
Notice:The oxygen sensor uses a permanently at-
tached pigtail and connector. This pigtail should not be
removed from the oxygen sensor. Damage or removal
of the pigtail or the connector could affect proper opera-
tion of the oxygen sensor. Do not drop the oxygen sen-
sor.
2. Disconnect the electrical connector.
3. Carefully remove the oxygen sensor from the exhaust
pipe.
Installation Notice
Tightening Torque
55 NSm (41 Ib-ft)
Important:A special anti-seize compound is used on
the oxygen sensor threads. This compound consists of
a liquid graphite and glass beads. The graphitewill burn
away, but the glass beadswill remain, making the sen-
sor easier to remove. New or serviced sensors will al-
ready have the compound applied to the threads. If a
sensor is removed from any engine and is to be rein-
stalled, the threads must have an anti-seize compound
applied before reinstallation.
4. Coat the threads of the oxygen sensor with an anti-
seize compound, if needed.
5. Installation should follow the removal procedure in
the reverse order.
