DTC P0111: Notes

DTC P0111 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P0111	IAT circuit performance problem
DETECTION CONDITION	If the intake air temperature is higher than the engine coolant temperature by 18°C {32.4°F} for 1.2 s with the ignition switch turn in the ON position, the PCM determines that there is an IAT sensor circuit range/performance problem. : Ignition switch is in the ON position when 6 h or more have passed since the ignition switch was turned off Diagnostic support note This is a continuous monitor (CCM). 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 is available. DTCs are stored in PCM memory.
POSSIBLE CAUSE	IAT sensor malfunction Poor connection at MAF/IAT sensor or PCM connector PCM malfunction
