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

DTC P0108:00 (PCM, VINs 7, L, M) 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 Ground circuit MAP sensor malfunction PCM malfunction
