Heated Oxygen Sensor

CAUTION:

• Do not over tighten air fuel ratio sensor 1 and heated oxygen sensor 2. Doing so may cause damage

to air fuel ratio sensor 1 and heated oxygen sensor 2, resulting in the “MIL” coming on.

• Before installing a new air fuel ratio sensor 1 and heated oxygen sensor 2, clean exhaust system

threads using oxygen sensor thread cleaner and apply anti-seize lubricant.

REMOVAL (RH)

1.

Remove engine assembly. Refer to 

EM-103, "Removal and Installation"

.

2.

Loosen nuts with power tool in reverse order as shown.

CAUTION:

Cover engine openings to avoid entry of foreign materials.

INSPECTION AFTER REMOVAL

Surface Distortion

• Check the surface distortion of the exhaust manifold mating sur-

face with straightedge and feeler gauge.

• If it exceeds the limit, replace exhaust manifold.
