OXYGEN SENSOR (O2S1)
Removal Procedure
1. Remove the air cleaner/resonator assembly. Refer to
Section 1B, SOHC Engine Mechanical.
2. Remove the oxygen sensor.
Disconnect the oxygen sensor connector (1).
Remove the oxygen sensor (2).
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. Take care when handling the
oxygen sensor. Do not drop the oxygen sensor.
D12F547A
Installation Procedure
1. Install in the reverse order of removal.
Important: 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 sen-
sor easier to remove. New or service sensors will al-
ready 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.
2. Install the oxygen sensor.
Tighten
Tighten the oxygen sensor to 35~44 Nm (26~33 lb-
ft).
