WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITIONS & POSSIBLE CAUSES

DTC P0111:00	IAT sensor circuit range/performance problem
DETECTION CONDITION	If the intake air temperature is higher than the engine coolant temperature by 18°C {32°F} for 1.2 s with the ignition switch is ON, the PCM determines that there is a IAT sensor circuit range/performance problem. . 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 is available. The DTC is stored in the PCM memory
POSSIBLE CAUSE	MAF/IAT sensor connector or terminal malfunction IAT sensor malfunction PCM connector or terminal malfunction PCM malfunction
