DTC P0107-00: Map Sensor Circuit Low Input: Notes

DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0107:00 MAP sensor circuit low input
DETECTION CONDITION 
  • The PCM monitors the input voltage from the MAP sensor. If the input voltage at the PCM terminal 1BW is below 0.08 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 check engine light 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.
FAIL-SAFE FUNCTION 
  • Estimates MAP using MAF sensor and engine speed.
  • Restricts the upper limit of the engine speed.
  • Inhibits the evaporative purge control.
POSSIBLE CAUSE 
  • MAP sensor/IAT sensor No.2 connector or terminals malfunction
  • Short to ground in wiring harness between the following terminals:
    • MAP sensor/IAT sensor No.2 terminal C-PCM terminal 1BO
    • MAP sensor/IAT sensor No.2 terminal D-PCM terminal 1BW
  • PCM connector or terminals malfunction
  • MAP sensor signal circuit and ground circuit are shorted to each other
  • Open circuit in wiring harness between MAP sensor/IAT sensor No.2 terminal C and PCM terminal 1BO
  • MAP sensor malfunction
  • PCM malfunction
G09073953
CAUTION:
  • Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
