Code P2197 2007 Ford Fusion Description
The P2197 code for a 2007 Ford Fusion indicates that the oxygen sensor signal for Bank 2 Sensor 1 is biased or stuck lean. This means that the oxygen sensor located in bank 2 of the engine is reporting a consistently lean air-fuel mixture to the engine control module (ECM) or powertrain control module (PCM). The ECM/PCM uses this information to adjust the fuel delivery to maintain the optimal air-fuel ratio for combustion. When the sensor is stuck lean, it can cause the engine to run too rich, leading to poor fuel efficiency, reduced performance, and increased emissions. If left unaddressed, this issue can potentially damage the catalytic converter and other engine components.
Common Causes of P2197 2007 Ford Fusion
- Faulty oxygen sensor
- Vacuum leaks in the intake system
- Fuel system issues (e.g., clogged fuel injectors)
- Exhaust leaks near the oxygen sensor
- Wiring or connector issues in the oxygen sensor circuit
Symptoms of P2197 2007 Ford Fusion
- Decreased fuel efficiency
- Rough idling or stalling
