DTC P0108: Notes
DTC P0108 [L3] DETECTION CONDITIONS AND POSSIBLE CAUSES
| DTC P0108 |
MAP sensor circuit high input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the MAP sensor. If input the voltage is above 4.92 V for 5
s, the PCM determines that the MAP sensor circuit has malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2/Mode12) is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- MAP sensor connector or terminal malfunction
- MAP sensor signal circuit shorts to constant voltage supply circuit
- MAP sensor malfunction
- Open circuit in wiring harness between MAP sensor terminal A and PCM terminal 2AV
- Open circuit in wiring harness between MAP sensor terminal D and PCM terminal 2AG
- PCM malfunction
