Code P2273 Ford Description

The P2273 Ford code indicates that the oxygen sensor signal for Bank 2 Sensor 2 is stuck rich. This means that the sensor is detecting an excessively high level of fuel in the exhaust gases, causing the engine to run rich (too much fuel relative to air). The oxygen sensor is responsible for monitoring 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.
