(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

PRECAUTION
1. DO NOT STOP ENGINE IMMEDIATELY AFTER PULL-
ING A TRAILER OR AFTER HIGH SPEED OR UPHILL
DRIVING. IDLE ENGINE FOR 20 - 120 SECONDS, DE-
PENDING ON HOW HARD VEHICLE HAS BEEN DRIV-
EN
2. AVOID SUDDEN ACCELERATION OR RACING IM-
MEDIATELY AFTER STARTING A COLD ENGINE
3. DO NOT RUN ENGINE WITH AIR CLEANER RE-
MOVED, AS THIS MAY CAUSE FOREIGN MATERIAL
TO ENTER AND DAMAGE IMPELLER WHEEL OPER-
ATING AT HIGH SPEED
4. IF A TURBOCHARGER IS FOUND TO BE DEFECTIVE
AND MUST BE REPLACED, CHECK FOR CAUSE, AND
REPAIR OR REPLACE FOLLOWING ITEMS AS NEC-
ESSARY

Engine oil level and quality

Conditions under which the turbocharger was used

Oil lines leading to the turbocharger
5. USE CAUTION WHEN REMOVING AND REINSTAL-
LING TURBOCHARGER ASSEMBLY. DO NOT DROP
IT OR KNOCK IT AGAINST ANYTHING OR GRASP IT
BY EASILY-DEFORMED PARTS, SUCH AS ACTUA-
TOR OR ROD, WHEN MOVING IT
6. USE CAUTION WHEN REMOVING AND REINSTAL-
LING EXHAUST GAS CONTROL VALVE ASSEMBLY.
DO NOT DROP IT OR KNOCK IT AGAINST ANYTHING
OR GRASP IT BY EASILY-DEFORMED PARTS, SUCH
AS ACTUATOR OR ROD, WHEN MOVING IT. CON-
TROL VALVE IS CERAMIC
7. BEFORE REMOVING TURBOCHARGER, PLUG IN-
TAKE AND EXHAUST PORTS AND OIL INLET TO PRE-
VENT ENTRY OF DIRT OR OTHER FOREIGN MATERI-
AL
8. IF REPLACING TURBOCHARGER, CHECK FOR AC-
CUMULATION OF SLUDGE PARTICLES IN OIL PIPES,
AND IF NECESSARY, REPLACE OIL PIPES
9. COMPLETELY REMOVE GASKET ADHERED TO LU-
BRICATION OIL PIPE FLANGE AND TURBOCHAR-
GER OIL FLANGE
10. WHEN REPLACING BOLT OR NUTS, USE ONLY AU-
THORIZED REPLACEMENT PARTS TO PREVENT
BREAKAGE OR DEFORMATION

20 cm
3 (1.2 cu in.) OF FRESH OIL INTO TURBOCHAR-
GER OIL INLET AND TURN IMPELLER WHEEL BY
HAND TO SPREAD OIL TO BEARING
12. IF OVERHAULING OR REPLACING ENGINE, CUT
FUEL SUPPLY AFTER REASSEMBLY AND CRANK
ENGINE FOR 30 SECONDS TO DISTRIBUTE OIL
THROUGHOUT ENGINE. THEN ALLOW ENGINE TO
IDLE FOR 60 SECONDS

ON-VEHICLE INSPECTION
1. INSPECT INTAKE AIR SYSTEM
Check for leakage or clogging between the air cleaner and
turbocharger inlet and between the turbocharger outlet and cyl-
inder head.

Clogged air cleaner ..Clean or replace air filter

Hoses collapsed or deformed .... Repair or replace

Leakage from connections .... Check each
connection and repair

Cracks in components .... Check and replace
2. INSPECT EXHAUST SYSTEM
Check for leakage or clogging between the cylinder head and
turbocharger inlet and between the turbocharger outlet and ex-
haust pipe.

Deformed components .... Repair or replace

Foreign material in passages .... Remove

Leakage from components .... Repair or replace

Cracks in components .... Check and replace
3. INSPECT EXHAUST GAS CONTROL
VALVE OPERATION
(a) Disconnect the air hose from the actuator.
(b) Using SST, apply approx. 49 kPa (0.50 kgf/cm
2, 7.1 psi)
of pressure to the actuator.
SST 09992-00242
(c) Check that the actuator push rod moves.
(d) Reconnect the air hose to the actuator.
If operation is not as specified, replace the control valve assem-
bly.
4. INSPECT TURBOCHARGING PRESSURE
(a) Using a 3-way connector, connect SST (turbocharger
pressure gauge) to the hose between the gas filter and
turbo pressure sensor.
SST 09992-00242
(b) While driving with the engine running at 5,600 rpm or
more with the throttle valve fully open in the 1st gear/L
range, check the turbocharging pressure.
Standard pressure:
61 - 75 kPa (0.62 - 0.76 kgf/cm
2, 8.8 - 10.8 psi)
If the pressure is less than that specified, check the intake and
exhaust systems for leakage. If there is no leakage, replace the
turbocharger assembly.
If the pressure is above specification, check if the actuator hose
is disconnected or cracked. If not, replace the turbocharger as-
sembly.
