MAP Sensor sense circuit high voltage
MAP Sensor sense circuit high voltage
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: –Default value of 1.013 BAR (29.92 in hg) used
Common causes
- MAP Sensor sensor ground circuit (to splice): open circuit MAP Sensor to ECM sense circuit: short circuit to high voltage MAP Sensor failure
- Manifold absolute pressure (MAP) sensor
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)
- Generic OBD often cannot read ABS — may need SDD/JLR tool for full module codes
