Code P2273 2011 Ford Fusion Description

The P2273 diagnostic trouble code (DTC) for a 2011 Ford Fusion indicates that the oxygen sensor signal for Bank 2 Sensor 2 is stuck rich. This means that the oxygen sensor located downstream of the catalytic converter on the second bank of cylinders is detecting a consistently high level of fuel in the exhaust gases. The oxygen sensor is responsible for monitoring the oxygen content in the exhaust and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the oxygen sensor signal is stuck rich, it can lead to a variety of performance issues and potential long-term effects on the vehicle.
