Code P2197 2008 Ford Fusion Description
The P2197 diagnostic trouble code (DTC) for a 2008 Ford Fusion indicates that the oxygen sensor signal for Bank 2 Sensor 1 is biased or stuck lean. This means that the oxygen sensor is detecting a consistently lean air-fuel mixture in the exhaust gases. The oxygen sensor plays a crucial role in monitoring the oxygen levels in the exhaust system, which helps the engine control module (ECM) adjust the air-fuel mixture for optimal combustion.
Common Causes of P2197 2008 Ford Fusion
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Fuel delivery issue
- ECM malfunction
- Exhaust system leak
Symptoms of P2197 2008 Ford Fusion
- Rough idling
- Hesitation during acceleration
- Decreased fuel efficiency
- Engine misfires
- Check Engine Light illuminated
