Code P0114 Mazda Description

The P0114 diagnostic trouble code (DTC) for Mazda vehicles refers to the Intake Air Temperature Sensor 1 Intermittent Or Erratic. This code indicates that the Engine Control Module (ECM) has detected a problem with the intake air temperature sensor, specifically that the signal being received is intermittent or erratic. The intake air temperature sensor plays a crucial role in the engine's performance by providing the ECM with data on the temperature of the incoming air. This information is essential for the ECM to adjust the air-fuel mixture and ignition timing for optimal engine performance and efficiency.
