• Never damage air fuel ratio sensor 1 and heated oxygen sensor 2.
• 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 concrete floor; use a new one.
9. Remove catalyst converter shroud upper.
10. Remove bolts and nut of catalyst converter turbocharger side.
11. Remove catalyst convertor. And keep a service area.
NOTE:
Slide the catalyst converter in a lateral direction to obtain work space for removing exhaust manifold
mounting nuts.
12. Remove heat insulator. Refer to
13. Disconnect water hoses from turbocharger as follows:
• Attach plug to prevent engine coolant leakage when engine coolant is not drained.
CAUTION:
Perform this step when the engine is cold.
14. Remove oil supply tube and oil return pipe. Refer to
15. Remove exhaust manifold cover. Refer to
.
16. Remove exhaust manifold mounting nuts.
17. Remove exhaust manifold with turbocharger.
18. Remove gasket of exhaust manifold.
19. Remove catalyst converter.
20. Remove gasket.
INSTALLATION
1. Install gasket between turbocharger and catalyst as shown in
the figure.
2. Install catalyst converter with the following procedure.

• 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.
