DTC P0111:00

IAT sensor circuit range/performance problem

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.
