(Possible Cause)
(Check Procedure and Correction Method)
Check intake air system, and repair or replace parts
as necessary. (See page TC-5)
Check intake air system, and repair or replace parts
as necessary. (See page TC-5)
Check exhaust system, and repair or replace parts
as necessary. (See page TC-5)
Check exhaust system, and repair or replace parts
as necessary. (See page TC-5) Check turbocharging pressure. (See page TC-5)
Turbocharging pressure:
61 - 75 kPa
(0.62 - 0.76 kgf/cm2, 8.8 - 10.8 psi)
If the pressure is below specifications, begin
diagnosis from item 2.
Check rotation of turbine shaft. If it does not turn or
turns with a heavy drag, replace the turbocharger
assembly.
Check axial and radial play of turbine shaft.
(See page TC-18)
Maximum axial play : 0.110 mm (0.0045 in.)
Maximum radial play: 0.173 mm (0.0068 in.)
If the play is greater than maximum, replace the
turbocharger assembly.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
HINT:
Before troubleshooting the turbocharger, first check the engine itself. (Valve clearance, engine compression,
ignition timing etc.)
1. INSUFFICIENT ACCELERATION, LACK OF POWER OR EXCESSIVE FUEL CONSUMPTION
Page 1785 of 1807
(Possible cause) (Check Procedure and Correction Method)
Check for deformed exhaust pipe, loose mounting
bolts or damaged gasket, and repair or replace as
necessary.
Refer to item 6 of INSUFFICIENT ACCELERATION,
LACK OF POWER OR EXCESSIVE FUEL
CONSUMPTION.
Check for loose, improperly installed or deformed
insulator mounting bolts, and repair or replace as
necessary.1. TURBOCHARGING HEAT

2. EXHAUST PIPE LEAKING
VIBRATING
3. ERRATIC TURBOCHARGER
OPERATION
(Possible Cause)(Check Procedure and Correction Method)
Check for oil leakage in exhaust system
Remove the turbine elbow from the turbocharger
and check for excessive carbon deposits on the
turbine wheel. Excessive carbon deposits
indicate a faulty turbocharger.
Check for oil leakage in intake air system.
Check for axial and radial play of turbine shaft
and replace the turbocharger if necessary.
(See page TC-18)
Maximum axial play : 0.110 mm (0.0045 in.)
Maximum radial play : 0.173 mm (0.0068 in.)
Some oil mist in the blowby from the PCV is
Do not mistake it for an oil leak from the
turbocharger.
