DTC P0111:00: Notes

DTC P0111:00	IAT sensor circuit range/performance problem
DETECTION CONDITION	The PCM compares the intake air temperature with the engine coolant temperature when the engine is running. If the intake air temperature is higher than the engine coolant temperature by 40 °C {72 °F} for 60 s , the PCM determines that there is an IAT sensor circuit range/performance problem. Diagnostic support note This is a continuous monitor (CCM). The check engine light 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.
