DESCRIPTION:
The fault code sets when the motor control module (MCM) does not receive a message from the exhaust gas recirculation (EGR) valve actuator.
MONITORED PARAMETER:
MCM communication from the EGR valve actuator.
TYPICAL ENABLING CONDITIONS:
Ignition on
MONITOR SEQUENCE:
None
EXECUTION FREQUENCY:
Always enabled
TYPICAL DURATION:
Two seconds
DASH LAMPS:
1. MIL
2. CEL
ENGINE REACTION:
None
VERIFICATION:
Ignition on
PROBABLE CAUSES:
1. If any voltage codes exist, fix those first.
2. EGR valve actuator pull rod.
3. EGR actuator.
4. EGR valve.
5. Wiring between the EGR actuator harness and the ECM.
