With Coolant Control Valve

DTC P0107:00 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 1X 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/Snapshot data is available.
  • 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
  • PCM connector or terminals malfunction
  • Short to ground in wiring harness between the following terminals:
  • MAP sensor/IAT sensor No. 2 terminal C-PCM terminal 1J
    • MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1X
  • MAP sensor signal circuit and ground circuit are shorted to each other
  • MAP sensor malfunction
  • PCM malfunction
