Code P0097 2012 Ford Fusion Description

The P0097 code for a 2012 Ford Fusion indicates a problem with the Intake Air Temperature Sensor 2 Circuit, specifically a low input signal. The Intake Air Temperature Sensor (IAT) is responsible for measuring the temperature of the air entering the engine. The Engine Control Module (ECM) uses this data to adjust the air-fuel mixture for optimal combustion. When the ECM detects a low input signal from the IAT Sensor 2 Circuit, it can lead to issues with engine performance, fuel efficiency, and emissions.
