Pcm Code E32, Open Map Sensor CKT: Action

PCM turns on SERVICE ENGINE SOON light. PCM sets BARO to 92 kPa. PCM uses a substitute MAP sensor value based on engine RPM and throttle switch status (open or closed).

NOTE: Test numbers refer to numbers on diagnostic chart.

Checks for sensor/PCM circuitry ability 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 PCM ability to respond to a 5-volt signal voltage on MAP input.
Fault is most likely at PCM connector or PCM. Before PCM is replaced, perform PFI CHART C-1, PCM REPLACEMENT CHECK.
