Code P032, Open Manifold Absolute Pressure (Map) Sensor: Action
PCM turns on MIL, sets BARO to 92 kPa, and uses a substitute MAP value based on engine RPM and throttle position switch status (open or closed). PCM disables long term fuel trim.
NOTE:
Test numbers refer to numbers on diagnostic chart.
- Checks if circuit from sensor to PCM is able to respond to a 5-volt signal on MAP input. A reading of 106-109 kPa means wiring and PCM are okay.
- Checks for 5-volt reference signal at sensor connector.
- Checks circuit No. 432 for short to ground.
- Checks if PCM is able to respond to a 5-volt signal voltage on MAP input.
- Fault is most likely at PCM connector or PCM. Before replacing PCM, check for damaged pins or poor connections.
