Code P2271 2011 Ford Fusion Description
The diagnostic trouble code P2271 for a 2011 Ford Fusion indicates that the oxygen sensor signal for Bank 1 Sensor 2 is stuck rich. This means that the oxygen sensor located after the catalytic converter on the bank of cylinders containing cylinder 1 is detecting a high level of fuel in the exhaust system. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases and sending this information to the engine control module (ECM) for fuel mixture adjustments. When the sensor is stuck rich, it means that the engine is running too rich, or using too much fuel compared to the amount of air present.
Common Causes of P2271 2011 Ford Fusion
- Faulty oxygen sensor
- Leaking fuel injector
- Clogged air filter
- Malfunctioning mass airflow sensor
- Problem with the fuel pressure regulator
Symptoms of P2271 2011 Ford Fusion
- Decreased fuel efficiency
