Engine Exhaust Gas Recirculation
(EGR) Valve Control : Not
Responding Properly The ECM detects the following conditions:
The signal from the NRS valve position sensor indicates
that the valve is not in the desired position.
This diagnostic code can be caused by a loss of the 5 VDC
supply to the NRS valve position sensor.
The ECM has been powered for at least 2 seconds.
If equipped, the warning lamp will come on. The ECM will
log the diagnostic code.
