P2272 2010 Ford Fusion Code - O2 Sensor Signal Biased/Stuck Lean Bank 2 Sensor 2

Quick Answer

The downstream heated oxygen sensor (HO2S) is forced rich and lean and monitored by the Powertrain Control Module (PCM). Common causes include Faulty O2 Sensor Bank 2 Sensor 2, Exhaust leaks, O2 Sensor Bank 2 Sensor 2 harness is open or shorted. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.
