Generator “CHARGE” circuit high voltage / request low
Generator “CHARGE” circuit high voltage / request low
Documented for: 2.0L gasoline; 2.5L/3.0L gasoline · System(s): EMS EOBD, EMS OBD II · Factory MIL flag: 2 · Default action: ECM Default: –Cooling fan speed increased
Common causes
- Generator to ECM “CHARGE” circuit: short circuit to high voltage Generator regulator failure Generator failure
- Barometric pressure (BARO) sensor
- incorporated in ECM - range/performance
Quick checks
- Confirm freeze-frame and conditions when the code set
- Inspect connectors, grounds, and harness for the circuit named in the code
- Compare live sensor values vs expected (unplugged/biased sensors are common)
