REMOVAL

PROCEDURE

1. REMOVE NO. 1 ENGINE UNDER COVER

2. REMOVE NO. 2 ENGINE UNDER COVER

3. REMOVE FRONT EXHAUST PIPE ASSEMBLY

4. REMOVE HEATED OXYGEN SENSOR

(a) Using SST, remove the heated oxygen sensor from the front exhaust pipe assembly.

SST: 09224-00011

Inspection

INSPECTION

PROCEDURE

1. INSPECT HEATED OXYGEN SENSOR

(a) Measure the resistance according to the value(s) in the table below.

Text in Illustration

*a	Component without harness connected (Heated Oxygen Sensor)

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 (HT1B) - 2 (+B)	20°C (68°F)	9 to 14 Ω
1 (HT1B) - 4 (E2)	-	10 kΩ or higher

If the result is not as specified, replace the heated oxygen sensor.

Installation

INSTALLATION

PROCEDURE

1. INSTALL HEATED OXYGEN SENSOR

HINT:

Perform "Inspection After Repair" after replacing the heated oxygen sensor (See page ).

(a) Using SST, install the heated oxygen sensor to the front exhaust pipe assembly.

Text in Illustration

*a	Length of SST 30 mm (1.18 in.)
*b	Length of Torque Wrench 300 mm (11.8 in.)

SST: 09224-00011

Torque:

without SST [Torque (N*m (kgf*cm, ft.*lbf))] :

44 N·m {449 kgf·cm, 32 ft·lbf}

with SST [Reading of Torque wrench (N*m (kgf*cm, ft.*lbf))] :

40 N·m {408 kgf·cm, 30 ft·lbf}

NOTICE:

If the heated oxygen sensor has been struck or dropped, replace it.

HINT:

This torque value is effective when SST is parallel to the torque wrench.
The "with SST" torque value is effective when using SST with a fulcrum length of 30 mm (1.18 in.).
The "with SST" torque value is effective when using a torque wrench with a fulcrum length of 300 mm (11.8 in.).
If using a torque wrench with a different length, or connecting the torque wrench and SST at an angle, refer to the alternate torque values (See page ).

2. INSTALL FRONT EXHAUST PIPE ASSEMBLY

3. INSPECT FOR EXHAUST GAS LEAK

4. INSTALL NO. 2 ENGINE UNDER COVER

5. INSTALL NO. 1 ENGINE UNDER COVER

6. PERFORM INITIALIZATION

(a) Perform "Inspection After Repair" after replacing the heated oxygen sensor (See page ).
