cylinders within one rotation of crankshaft with all conditions met.
MONITORED PARAMETER:
Injection quantity
TYPICAL ENABLING CONDITIONS:
1. Engine speed between 500 and 1600 rpm.
2. Engine torque load between 25 and 75%.
3. All cylinders are active, no fault reactions .
4. Engine speed/torque is steady.
5. Coolant temperature is greater than 62°C (144°F) and less than 114°C
(237°F).
6. Fuel temperature is greater than 0°C (32 °F) and less than 150°C (302°F)
MONITOR SEQUENCE:
Always when enabling conditions are met.
EXECUTION FREQUENCEY:
Always
TYPCIAL DURATION:
1000 revolutions
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERIFICATION:
Ensure the ignition has been off for a minimum of five minutes prior to the last ignition on. Meet
all enabling conditions. 15 minute road test.
POSSIBLE CAUSES:
1. Cylinder kit failure.
2. Valve train failure.
3. Lash adjustments.
4. Fuel injector.
