Possible Causes
- Electrical Cause
- Mechanical Cause
- Control Module Signal Name
- Circuit reference Supply I_A_MAP
- Monitor Description
- Pressure sensor plausibility check against maximum modeled manifold pressure
- Manifold absolute pressure and temperature sensor circuit - Wiring integrity short circuit to ground, short circuit to power, open circuit, high resistance
- Connector is disconnected, connector pin is backed out, connector pin corrosion
- Manifold absolute pressure and temperature sensor failure
- Intake manifold air leak (loose or missing component)
- Breather system leak (loose or missing component)
- Blocked air filter
- Carbon build up around throttle
- Damaged/restricted exhaust system
