DTC P0112: Notes
DTC P0112 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0112 |
IAT circuit low input |
| DETECTION CONDITION |
- The PCM monitors the IAT sensor signal at PCM terminal 1AT. If the PCM detects IAT sensor voltage of 0.16 V or below
, the PCM determines that the IAT 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 the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- IAT sensor malfunction
- Connector or terminal malfunction
- Short to ground circuit between MAF/IAT sensor terminal D and PCM terminal 1AT
- Short each harness IAT sensor terminal D and E
- PCM malfunction
