DTC P0108: Notes
DTC P0108 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0108 |
MAP sensor circuit high input |
| DETECTION CONDITION |
- PCM monitors input voltage from the MAP sensor when the intake air temperature is above -10°C {14°F}
. If the input voltage is above 4.9 V
, the PCM determines that MAP sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition during first drive cycle.
- FREEZE FRAME DATA is available.
- DTCs are stored in the PCM memory.
|
| POSSIBLE CAUSE |
- MAP sensor malfunction
- Connector or terminal malfunction
- Open circuit in the wiring harness between MAP sensor terminal A and PCM terminal 2H
- Open circuit in the wiring harness between MAP sensor terminal D and PCM terminal 1J
- MAP sensor signal circuit short to the constant voltage supply circuit
- PCM malfunction
