DTC P0108-00: Map Sensor Circuit High Input: Outline

DTC P0108:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location MAP sensor circuit high input
Detection condition
  • The PCM monitors the input voltage from the MAP sensor. If the input voltage at the PCM terminal 1X is above 4.77 V for 5 s, the PCM determines that the MAP sensor circuit has a malfunction.
Fail-safe
  • 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 power supply in any of the following MAP sensor circuits.
    • Power supply circuit
      • Signal circuit
  • Short circuit in MAP sensor power supply circuit and signal circuit
  • Open circuit in any of the following MAP sensor circuits.
    • Signal circuit
