| DTC P0112:00 |
IAT sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors the IAT sensor signal. If the PCM detects that the IAT sensor voltage is below 0.16 V
for 5 s
, 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 during first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- The DTC is stored in the PCM memory.
|
| POSSIBLE CAUSE |
- MAF/IAT sensor connector or terminal malfunction
- Short to ground in wiring harness between MAF/IAT sensor terminal D and PCM terminal 1AT
- PCM connector or terminal malfunction
- Short circuit in IAT sensor signal circuit and ground circuit each other
- IAT sensor malfunction
- PCM malfunction
