Code P032, Open Map Sensor Circuit: Action
PCM turns on MIL. PCM disables long term fuel trim and uses a substitute MAP value based on engine RPM and throttle switch status (open or closed). PCM disables EVAP control solenoid. PCM disables torque management and transaxle shift adapts are maintained at current levels.
- PD02 will read 10-16 kPa if MAP sensor or related circuit is open.
- Checks for 5-volt reference signal at sensor connector. A reading of 103-105 kPa means that wiring and PCM are okay.
- Checks circuit No. 432 for short to ground and circuits No. 432 and 474 and MAP sensor circuit for open.
- Checks circuit No. 432 for short to ground.
- Checks if 5-volt signal is reaching PCM. If signal is present, replace PCM.
