Upstream Oxygen Sensor

Removal

1. Turn off all the electrical equipment and ignition switch.
2. Disconnect the negative battery cable.
3. Remove the engine trim cover assembly (

See page 10-10

).

4. Remove the upstream oxygen sensor.

a. Remove and disconnect the upstream oxygen sensor

connector (arrow) from bracket.

b. Remove 4 fixing bolts (arrow) from exhaust manifold

heat insulator, and remove the exhaust manifold heat
insulator.



(Tightening torque: 23 ± 2 N·m)

c. Remove the upstream oxygen sensor (arrow) from

precatalytic converter assembly.



(Tightening torque: 40 - 60 N·m)

WARNING

 Temperature of exhaust system is very high when engine is running. Before removal and installation, you

must make sure that the engine has stopped running; otherwise there is a risk of scald injury.

 Be sure to wear necessary safety equipment when repairing to prevent accidents.
 Try to prevent body paint surface from being scratched during removal and installation.
