| DTC P0113:00 |
IAT sensor No. 1 circuit high input |
| DETECTION CONDITION |
- The PCM monitors the IAT sensor No. 1 signal. If the PCM detects that the IAT sensor No. 1 voltage at the PCM terminal 2U is above 4.62 V
for 5 s
, the PCM determines that the IAT sensor No. 1 circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA (Mode 2)/Snapshot data is available.
- DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Fixes the intake air temperature (for engine control) at 20 °C {68 °F}
.
- Inhibits the fuel cut control during shift change.
|
| POSSIBLE CAUSE |
- MAF sensor/IAT sensor No. 1 connector or terminals malfunction
- PCM connector or terminals malfunction
- IAT sensor No. 1 malfunction
- Short to power supply in wiring harness between MAF sensor/IAT sensor No. 1 terminal A and PCM terminal 2U
- Open circuit in wiring harness between the following terminals:
- MAF sensor/IAT sensor No. 1 terminal A-PCM terminal 2U
- MAF sensor/IAT sensor No. 1 terminal B-PCM terminal 2AY
- PCM malfunction
