Code P1113 Mazda Description

The P1113 code for Mazda vehicles indicates a problem with the Intake Air Temperature (IAT) circuit being open or shorted. The IAT sensor measures the temperature of the incoming air into the engine, which is crucial for the engine control module to adjust the air-fuel mixture for optimal performance. When the circuit is open or shorted, the ECU may not receive accurate temperature readings, leading to potential issues with engine performance, fuel efficiency, and emissions.
