DTC P0103: Notes
DTC P0103 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0103 |
MAF circuit high input |
| DETECTION CONDITION |
- The PCM monitors the input voltage from the MAF sensor when the engine is running. If the input voltage at PCM terminal 1AK is 4.9 V or above
, the PCM determines that the MAF circuit has a 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 is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- MAF sensor malfunction
- Connector or terminal malfunction
- Short to power circuit between MAF/IAT sensor terminal C and PCM terminal 1AK
- Open circuit between MAF/IAT sensor terminal B and PCM terminal 1P
- PCM malfunction
