(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.

PROBLEM SYMPTOMS TABLE
HINT:
Before troubleshooting the turbocharger, first check the engine itself. (Valve clearance, engine compression,
