Code P2197 2011 Ford Fusion Description
The P2197 code for a 2011 Ford Fusion indicates an issue with the oxygen sensor signal being biased or stuck lean on Bank 2 Sensor 1. The oxygen sensor, also known as the O2 sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the sensor signal is biased or stuck lean, it means that the ECM is receiving a signal indicating a lean air-fuel mixture even when it may not be the case. This can lead to incorrect fuel delivery, affecting the engine's performance, fuel efficiency, and emissions.
Common Causes of P2197 2011 Ford Fusion
- Faulty oxygen sensor
- Wiring or connector issues
