Heated Oxygen Sensor

REMOVAL

CAUTION:
- The procedures should be performed by at least 2 people.
- Wear protective gloves when removing the exhaust pipe.
- The exhaust pipe is extremely hot immediately after the engine has stopped.
- Confirm that the exhaust pipe has cooled down before removing it.

1. REMOVE PROPELLER SHAFT HEAT INSULATOR (for 4WD)`
2. REMOVE FRONT PROPELLER SHAFT ASSEMBLY (for 4WD)
3. REMOVE FRONT NO. 2 EXHAUST PIPE ASSEMBLY (except Regular Cab Standard Deck)
4. REMOVE FRONT NO. 2 EXHAUST PIPE ASSEMBLY (for Regular Cab Standard Deck)
5. REMOVE FRONT EXHAUST PIPE ASSEMBLY

6. REMOVE HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
a. Using SST, remove the sensor.
SST 09224-00010

7. REMOVE HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)
a. Using SST, remove the sensor.
SST 09224-00010

INSTALLATION

1. INSTALL HEATED OXYGEN SENSOR (for Bank 2 Sensor 2)
a. Install the sensor to the exhaust pipe by hand.

2. INSTALL HEATED OXYGEN SENSOR (for Bank 1 Sensor 2)
a. Install the sensor to the exhaust pipe by hand.

b. Using SST, tighten the sensor.
SST 09224-00010

Torque: without SST 44 N.m (449 kgf.cm, 32 ft.lbf) with SST 40 N.m (408 kgf.cm, 30 ft.lbf)

HINT:
- Use a torque wrench with a fulcrum length of 30 cm (11.8 in.). If using a torque wrench with a length that is not 30 cm (11.8 in.), calculate the torque specification for the torque wrench and SST based on the "without SST" torque specification.
- Make sure SST and the wrench are connected in a straight line.

3. INSTALL FRONT EXHAUST PIPE ASSEMBLY
4. INSTALL FRONT NO. 2 EXHAUST PIPE ASSEMBLY (for Regular Cab Standard Deck)
5. INSTALL FRONT NO. 2 EXHAUST PIPE ASSEMBLY (except Regular Cab Standard Deck)
6. INSTALL FRONT PROPELLER SHAFT ASSEMBLY (for 4WD)
7. INSTALL PROPELLER SHAFT HEAT INSULATOR (for 4WD)
8. INSPECT FOR EXHAUST GAS LEAK
