Code P0097 Mazda Description

The P0097 diagnostic trouble code (DTC) for Mazda vehicles specifically refers to the Boost Air Temperature Sensor Circuit Low Input. This code indicates that there is an issue with the boost air temperature sensor circuit, specifically that the input signal is lower than the expected range. The boost air temperature sensor plays a crucial role in monitoring the temperature of the air entering the engine's intake system. This information is essential for the engine control module (ECM) to adjust the air-fuel mixture and ignition timing to optimize engine performance.
