ACTION
2
Does engine speed continue at fast idle?
Yes
Go to symptom troubleshooting No.8 “Fast idle/
runs on”.
No
Go to next step.
3
Remove thermostat and inspect operation.
(See Section E)
Is thermostat okay?
Yes
Inspect condenser fan and main fan operation.
If both or either fan operate abnormally, inspect
for following:
• Cooling fan relay is stuck closed.
• Condenser fan relay is stuck closed.
• Short to GND between cooling fan relay and
PCM terminal 47 (except for GF4A-EL
models) or 98 (for GF4A-EL models)
• Short to GND between condenser fan relay
and PCM terminal 17 (for GF4A-EL models)
or 45 (except for GF4A-EL models)
• Circuit between cooling fan relay and fan
motor is shorted to battery supply line
• Circuit between condenser fan relay and fan
motor is shorted to battery supply line
No
Access ECT V PID on NGS tester.
Inspect for both ECT V and temperature gauge
on instrument cluster readings.
If temperature gauge on instrument cluster
indicates normal range but ECT V is not same
as temperature gauge reading, inspect ECT
sensor.
If temperature gauge on instrument cluster
indicates cold range but ECT voltage is normal,
inspect temperature gauge and heat gauge unit.

Exhaust smoke
DESCRIPTION
• Blue, black, or white smoke from exhaust system
POSSIBLE
CAUSE
Blue smoke (Burning oil):
• PCV valve malfunction
• Engine internal oil leakage
White smoke (Water in combustion):
• Cooling system (coolant loss) malfunction
• Engine internal coolant leakage
Black smoke (Rich fuel mixture):
• Air cleaner restriction
• Intake-air system is collapsed or restricted.
•
Fuel return line is restricted.
•
Excessive fuel pressure
•
Improper engine compression
•
Injector fuel leakage
•
Ignition system malfunction
Warning
•
Following troubleshooting flow chart contains fuel system diagnosis and repair
procedures. Read following warnings before performing fuel system service:
— Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage.
Always keep sparks and flames away from fuel.
— Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries
or death and damage. Fuel can also irritate skin and eyes. To prevent this, always
complete “BEFORE REPAIR PROCEDURE” and “AFTER REPAIR PROCEDURE”. (See
Section F)
Caution
•
Disconnecting/connecting the quick release connector without cleaning it may possibly
cause damage to the fuel pipe and quick release connector. Always clean the quick
release connector joint area before disconnecting/connecting, and make sure that it is
free of foreign material.
