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 CONDITION & POSSIBLE CAUSE

DTC P0111:00	IAT sensor circuit range/performance
DETECTION CONDITION	Indicates the IAT rationality test has failed This DTC indicates that the IAT value is higher than a calibrated value and could prevent 1 or more on-board diagnostic (OBD) monitors from completing The PCM runs this logic after an engine off and a calibrated soak period (typically 6 hours) This soak period allows IAT and CHT to stabilize and not differ by more than a calibrated value DTC P0111:00 is set when- the IAT at engine start exceeds the CHT by more than a calibrated value, typically 17 °C {63 °F}.
POSSIBLE CAUSE	IAT sensor malfunction
