DTC P0108:00

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 1BW is above 4.89 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 power supply 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
•  MAP sensor power supply circuit and signal circuit are shorted to each other
•  Open circuit in wiring harness between the following terminals:
―  MAP sensor/IAT sensor No.2 terminal D—PCM terminal 1BW
