DTC P0108: Notes

DTC P0108 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P0108 MAP sensor circuit high input
DETECTION CONDITION 
  • The PCM monitors the input voltage from the MAP sensor when the intake air temperature is above -10 °C {14 °F}.  If input the voltage at PCM terminal 2AL is above 4.92 V,  the PCM determines that the MAP sensor circuit has malfunction.

    Monitoring Condition 

    • Calculated load: 13-32% 
  • 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.
  • DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • MAP sensor malfunction
  • Connector or terminal malfunction
  • Open circuit in wiring harness between MAP sensor terminal A and PCM terminal 2AA
  • Open circuit in wiring harness between MAP sensor terminal D and PCM terminal 2AL
  • MAP sensor signal circuit shorts to constant voltage supply circuit
  • PCM malfunction
