DTC P0108-00: Map Sensor Circuit High Input: Notes
DTC P0108:00 (PCM, SKYACTIV-G 2.5T) DETECTION CONDITION AND POSSIBLE CAUSE
| 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 1BD 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
- MAP sensor malfunction
- Short to power supply in wiring harness between the following terminals:
- MAP sensor/IAT sensor No. 2 terminal C-PCM terminal 1CM
- MAP sensor/IAT sensor No. 2 terminal D-PCM terminal 1BD
- 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 1BD
- MAP sensor/IAT sensor No. 2 terminal A-PCM terminal 1CJ
- PCM malfunction
