This means that the oxygen sensor located downstream of the catalytic converter on the bank 1 side of the engine is detecting a consistently high level of fuel in the exhaust gases. The oxygen sensor is responsible for measuring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion.
Common Causes of P2271 2009 Ford Fusion
- Faulty oxygen sensor
- Vacuum leak
- Fuel injector issue
- Malfunctioning mass airflow sensor
- Fuel system problem
Symptoms of P2271 2009 Ford Fusion
- Decreased fuel efficiency
