DTC P0107 [L3]: Notes

DTC P0107 (L3) DETECTION CONDITION & POSSIBLE CAUSES

DTC P0107 MAP sensor circuit low 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 the input voltage at PCM terminal 2AG is below 0.1V for 5s  , 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.
  • The DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • Connector or terminal malfunction
  • Open circuit in the wiring harness between MAP sensor terminal C and PCM terminal 2AU
  • MAP sensor malfunction
  • Short to ground in wiring harness between MAP sensor terminal D and PCM terminal 2AG
  • MAP sensor signal circuit and MAP sensor ground circuit are shorted each other
  • PCM malfunction
