MAP Sensor Reading Exceeds Barometric Pressure
2004-2008 Chrysler Crossfire 3.2L V6
Description
The PCM has detected that the MAP sensor reading exceeds the barometric pressure reading, which is physically impossible under normal conditions. This indicates a sensor fault or a significant pressure anomaly in the intake manifold.
Symptoms
- Check Engine Light
- Poor engine performance
- Rough idle
- Black smoke from exhaust
- Poor fuel economy
Common Causes
- Faulty MAP sensor
- MAP sensor vacuum hose disconnected or leaking
- Short circuit in MAP sensor wiring
- PCM reference voltage issue
- Intake manifold pressure anomaly
Diagnostic Steps
- Compare MAP sensor reading at key-on engine-off to barometric pressure
- Inspect MAP sensor vacuum hose for leaks or disconnection
- Test MAP sensor output voltage range
- Check 5V reference circuit
- Verify MAP sensor wiring for shorts
Repair Notes
Replace the MAP sensor if its reading exceeds barometric pressure with the engine off.
