REMOVAL

1.

Remove exhaust front tube. Refer to 

EX-5, "Exploded View"

.

2.

Remove exhaust manifold cover.

3.

Remove the air fuel ratio sensor 1.

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

sensor thread cleaner tool (commercial service tool) and apply anti-seize lubricant.

• Never over torque air fuel ratio sensor 1. Doing so may cause damage to air fuel ratio sensor 1,

resulting in the “MI” coming on.

• Prevent rust preventives from adhering to the sensor body.

INSPECTION AFTER REMOVAL

Surface Distortion

• Using feeler gauge (A) and straightedge (B), check the surface dis-

tortion of exhaust manifold mating surface in each exhaust port
and entire part.

• If it exceeds the limit, replace exhaust manifold.
