REMOVAL
1. Remove heated oxygen sensors.
●Follow below steps to remove each heated oxygen sensor.
a. Remove engine undercover.
b. Disconnect harness connector of each heated oxygen sensor, and harness from bracket and middle
clamp.
c. Using heated oxygen sensor wrench, remove heated oxygen
sensors.
CAUTION:
●Be careful not to damage heated oxygen sensor.
●Discard any heated oxygen sensor which has been
dropped from a height of more than 0.5 m (19.7 in) onto a
hard surface such as a concrete floor; use a new one.
2. Remove exhaust manifold and three way catalyst assembly.
a. Remove exhaust manifold cover lower.
b. Remove exhaust front tube. Refer to EX-2, "

●Disregard the numerical order No. 6 and 7 when loosening.
3. Remove exhaust manifold and three way catalyst loosening nuts
in reverse order in the figure.
INSPECTION AFTER REMOVAL
Surface Distortion
Use a reliable straightedge and feeler gauge to check the flatness of
exhaust manifold fitting surface.
INSTALLATION
Install in the reverse order of removal paying attention to the following.
Exhaust Manifold Nuts
●Tighten nuts in the numerical order shown in the figure.
●No. 6 and 7 indicate double tightening of bolts No. 1 and 3.
Heated Oxygen Sensor
CAUTION:
Do not over torque the heated oxygen sensor. Doing so may cause damage to the heated oxygen sen-
sor, resulting in the MIL coming on.
