Code P2198 2010 Ford Fusion Description
The P2198 code for a 2010 Ford Fusion indicates that the oxygen sensor signal for Bank 2 Sensor 1 is biased or stuck rich. This means that the oxygen sensor is detecting an excessively rich air-fuel mixture in the exhaust gases. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the oxygen sensor signal is biased rich, it can lead to poor fuel economy, reduced engine performance, and increased emissions.
Common Causes of P2198 2010 Ford Fusion
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Fuel injector malfunction
- Issues with the engine's air intake system
- Exhaust system leaks
Symptoms of P2198 2010 Ford Fusion
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
