EXHAUST SYSTEM

- Using heated oxygen sensor wrench [SST: KV10114400] (A),

removal heated oxygen sensor 2 

.

CAUTION:

Discard any sensor which has been dropped from a height of
more than 0.5 m (19.7 in) onto a hard surface such as a con-
crete floor; use a new one.

INSTALLATION

Note the following, and install in the reverse order of removal.

CAUTION:

• Always replace gaskets with new ones when reassembling.
• Discard any heated oxygen sensor 2 which has been dropped onto a hard surface such as a con-

crete floor. Use a new one. 

• Before installing a new heated oxygen sensor 2, clean exhaust system threads using the heated oxy-

gen sensor thread cleaner [commercial service tool (J-43897-18 or J-43897-12)] and apply anti-seize
lubricant (commercial service tool).

• Never over torque heated oxygen sensor 2. Doing so may cause damage to the heated oxygen sen-

sor 2, resulting in the “MIL” coming on. 

• If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat

insulator, remove them.

• When installing heat insulator avoid large gaps or interference between heat insulator and each

exhaust pipe.

• Remove deposits from the sealing surface of each connection. Connect them securely to avoid gas

leakage. 

• Temporarily tighten mounting nuts and bolts. Check each part for unusual interference and mount-

ing rubber interference, and then tighten them to the specified torque. 

• When installing each mounting rubber, avoid twisting or unusual extension in up/down, front/rear

and right/left directions.

• Install mounting rubber, refer to the following instructions,
- Install slit of the mounting rubber 

 is in a horizontal direction.

INSPECTION AFTER INSTALLATION

• Check clearance between tail tube and rear bumper is even.
• With engine running, check exhaust tube joints for gas leakage and unusual noises.
• Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue

stress. Improper installation could result in excessive noise and vibration.
