Code P0111 Acura Description

The Intake Air Temperature (IAT) Sensor 1 is a thermistor that detects intake air temperature, and it is used for air/fuel ratio feedback control to compensate for the atmospheric density fluctuations that accompany changes in intake air temperature. IAT Sensor 1 resistance varies depending on temperature. The output voltage and the sensor resistance increase as the intake air temperature decreases. Conversely, the output voltage and the sensor resistance decrease as the intake air temperature increases. If the intake air temperature is a specified value for a specified time, the Powertrain Control Module (PCM) detects a malfunction and stores a Diagnostic Trouble Code (DTC).
