DTC P0112: Notes
DTC P0112 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0112 |
IAT circuit low input |
| DETECTION CONDITION |
- The PCM monitors IAT sensor signal at PCM terminal 15. If the PCM detected IAT sensor voltage below 0.16 V
, the PCM determines that the IAT sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.
- PENDING CODE is available if the PCM detects the above malfunction condition.
- FREEZE FRAME DATA is available.
- DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- IAT sensor malfunction
- Short to ground circuit between MAF/IAT sensor terminal F and PCM terminal 15
- Short each harness IAT signal circuit and IAT ground circuit.
- Poor connection at MAF/IAT sensor or PCM connector.
- PCM malfunction
