Code P0097 2011 Ford Fusion Description

The P0097 diagnostic trouble code (DTC) for a 2011 Ford Fusion indicates that there is a low input signal from the Intake Air Temperature Sensor 2 circuit. This sensor is responsible for measuring the temperature of the air entering the engine, which is essential for the engine control module (ECM) to adjust the air-fuel mixture ratio for optimal combustion. A low input signal suggests that the sensor is reading a temperature that is lower than expected, which can lead to incorrect fuel delivery and potentially affect the engine's performance and efficiency.
