• Tighten in numerical order as shown in the figure.

- Install catalyst converter (base on stud position 1).

- Temporary assemble 2 (no priority).

- Temporary assemble 3, 4.

- Tightening 5, 6 and 7.

- Tightening again 8, 9 and 10.

- Temporary assemble 11.

- Tightening 12,13,14,and 15.

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

A/F sensor 1 and Heated oxygen sensor 2 

• Using heated oxygen sensor wrench [SST: KV10117100 (J-

3647-A)], install A/F sensor 1 and heated oxygen sensor 2.

CAUTION:

• Before installing a new sensors, 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. 

• Never apply excessive torque to sensors. Doing so may

cause damage to sensors, resulting in the “MIL” illumi-

nating.

• Prevent rust preventives from adhering to the sensor

body.

Inspection

INFOID:0000000012197267

INSPECTION PROCERDURE

Trouble Diagnosis of Turbocharger

Check items before trouble diagnosis 
1. Check that the engine oil level is between L (Low level) and H (High level) of the oil level gauge. [When

the engine oil amount is more then H (High level), the engine oil flows into the inlet duct through the blow-

by gas passage, and the turbocharger is misjudged failure.] 

2. Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after

driving.

• Replace the exhaust manifold and turbocharger assembly when any malfunction is found after unit

inspections specified in the table below.

• If no malfunction is found after the unit inspections, judge that the turbocharger body has no non-stan-

dard conditions. Check the other parts again.
