| DETECTION CONDITION |
- If the intake air temperature is higher than the engine coolant temperature by 24 °C {43 °F} for 20 s
with the ignition switch is ON*, the PCM determines that there is a IAT sensor circuit range/performance problem. (TYPE A)
- If the intake air temperature is higher than the engine coolant temperature by 24 °C {43 °F} for 20 s
or the intake air temperature is lower than the engine coolant temperature by -48 °C {-86 °F} for 20 s
with the ignition switch is ON*, the PCM determines that there is a IAT sensor circuit range/performance problem. (TYPE B)
*: Ignition switch is ON when 6 h or more
have passed since the ignition was switched off.
Diagnostic support note
- This is a continuous monitor (CCM).
- The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available 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.
