Code P032, Open Map Sensor Circuit: Action

PCM turns on MIL. PCM sets BARO to 92 kPa and uses a substitute MAP value based on engine RPM and throttle switch status (open or closed). PCM disables long term fuel trim.

1. 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.
2. Checks for 5-volt reference signal at sensor connector.
3. Checks circuit No. 432 for short to ground.
4. Checks if PCM is able to respond to a 5-volt signal on MAP input.
5. Fault is most likely at PCM connector or PCM. Before replacing PCM, check for damaged pins or poor connections.
