REMOVAL
WARNING:
Perform the work when the exhaust and cooling system have completely cooled down.
1. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
2. Drain engine coolant. Refer to CO-11, "
Changing Engine Coolant" .
CAUTION:

Perform this step when the engine is cold.

Do not spill engine coolant on drive belts.
3. Remove air cleaner case and air duct. Refer to EM-17, "
AIR CLEANER AND AIR DUCT" .
4. Remove front and rear engine undercover and front cross bar with power tool.
5. Disconnect heated oxygen sensors 2 (bank 1 and bank 2) harness connectors.
1. Heated oxygen sensor 2 (bank 1) 2. Three way catalyst (right bank) 3. Gasket
4. Air fuel ratio sensor 1 (bank 1) 5. Exhaust manifold cover (right bank) 6. Exhaust manifold (right bank)
7. Exhaust manifold (left bank) 8. Exhaust manifold cover (left bank) 9. Three way catalyst (left bank)

6. Using the heated oxygen sensor wrench (SST), remove heated oxygen sensors 2 (bank 1 and bank 2).
CAUTION:

Be careful not to damage heated oxygen sensor.

Discard any heated oxygen sensor which has been
dropped onto a hard surface such as a concrete floor;
replace with a new sensor.
7. Remove exhaust mounting bracket between three way catalysts (right and left bank) and transmission. Refer to EX-3, "
EXHAUST SYSTEM" .
8. Remove three way catalysts (right and left bank).
9. Disconnect air fuel ratio sensor 1 (bank 1 and bank 2) harness connectors and remove harness clip.
10. Using the heated oxygen sensor wrench (SST), remove air fuel ratio sensor 1 (bank 1 and bank 2).
CAUTION:

Be careful not to damage air fuel ratio sensor.

Discard any air fuel ratio sensor which has been dropped
onto a hard surface such as a concrete floor; replace with
a new sensor.
11. Remove water pipe and heater pipe on both right and left side. Refer to CO-29, "
WATER OUTLET AND
WATER PIPING" .
12. Remove exhaust manifold cover (right and left bank).
13. Loosen mounting nuts in the reverse order as shown in the fig- ure to remove exhaust manifold with power tool.
NOTE:
Disregard the numerical order No. 7 and 8 in removal.
14. Remove gaskets. CAUTION:
Cover engine openings to avoid entry of foreign materials.

Air Fuel Ratio Sensor and Heated Oxygen Sensor
CAUTION:

Before installing a new air fuel ratio sensor and new heated oxygen sensor, clean exhaust system
threads using heated oxygen sensor thread cleaner tool (Commercial Service Tool: J-43897-18 or
J-43897-12) and apply anti-seize lubricant.

Do not over torque air fuel ratio sensor and heated oxygen sensor. Doing so may cause damage to
air fuel ratio sensor and heated oxygen sensor, resulting in the “MIL” coming on.
