  • PCM monitors input voltage from the MAP sensor when the intake air temperature is above -10°C {14°F}.  If the input voltage is below 0.10 V, the PCM determines that the MAP sensor circuit has a malfunction.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA is available.
  • DTCs are stored in the PCM memory.

  • MAP sensor malfunction
  • Connector or terminal malfunction
  • Short to ground in the wiring harness between MAP sensor terminal D and PCM terminal 2AG
