DTC P0113: Notes
DTC P0113 DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0113 |
IAT circuit high input |
| DETECTION CONDITION |
- The PCM monitors the IAT sensor signal. If the PCM detected IAT sensor voltage above 4.9 V
, 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 first drive cycle.
- FREEZE FRAME DATA is available.
- DTCs are stored in the PCM memory.
|
| POSSIBLE CAUSE |
- IAT sensor malfunction
- Open circuit between MAF/IAT sensor terminal D and PCM terminal 2V
- Short to the power supply between MAF/IAT sensor terminal D and PCM terminal 2V
- Open circuit between MAF/IAT sensor terminal E and PCM terminal 2H
- Poor connection at the MAF/IAT sensor or the PCM connector.
- PCM malfunction
