package instructions. Do not immerse the fuel rails
in liquid cleaning  solvent. Use care in removing
the fuel rail assembly to prevent damage to the
electrical connectors and injector  spray tips.
Prevent dirt and other contaminants from entering
open lines and passages. Fittings should  be
capped and holes plugged during service.

OXYGEN SENSOR

Removal and Installation Procedure

1. Disconnect the negative battery cable.

Notice: The oxygen sensor uses a permanently
attached 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 operation of the oxygen sensor. Do
not drop the oxygen sensor.

2. Disconnect the electrical connector.

3. Carefully remove the oxygen sensor from the

exhaust pipe.

Installation Notice

Tightening Torque

6 N•m (53 lb-in)

Tightening Torque

55 N•m (41 lb-ft)

4. Remove the pedal and sensor assembly.

5. Installation should follow the removal procedure

in the reverse order.

Important: A special anti-seize compound is used
on  the oxygen sensor threads. This compound
consists of aliquid graphiteand 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 havean antiseize 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.
