DTC P0108:00: Notes

DTC P0108:00 (L3 WITH TC) DETECTION CONDITION & POSSIBLE CAUSES

DTC P0108:00 MAP sensor circuit high input
DETECTION CONDITION 
  • The PCM monitors the input voltage from the MAP sensor. If the input voltage is above 4.92 V  for 5 s  , the PCM determines that the MAP sensor circuit has a malfunction.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
  • FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • MAP sensor/boost air temperature sensor connector or terminals malfunction
  • PCM connector or terminals malfunction
  • Short to power supply in wiring harness between MAP sensor/boost air temperature sensor terminal D and PCM terminal 2AG
  • MAP sensor power supply circuit and signal circuit are shorted to each other.
  • Open circuit in wiring harness between the following terminals:
    • MAP sensor/boost air temperature sensor terminal D-PCM terminal 2AG
    • MAP sensor/boost air temperature sensor terminal A-PCM terminal 2AV
  • MAP sensor malfunction
  • PCM malfunction
