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

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. This checks PCM ability to respond to a 5-volt signal on MAP input. A reading of 106-109 kPa means wiring and PCM are okay.
  2. This checks for 5-volt reference signal at sensor connector.
  3. This checks circuit No. 432 for short to ground.
  4. This checks PCM's ability to respond to a 5-volt signal voltage on MAP input.
