P2297 Lincoln Code - Oxygen Sensor Out of Range During Deceleration Bank 1 Sensor 1
Quick Answer
During a Deceleration Fuel Shut-Off (DFSO) event, the Powertrain Control Module (PCM) monitors how quickly the rear heated oxygen sensor (HO2S) switches from rich to lean. Common causes include Exhaust leaks before or near the Rear Heated Oxygen Sensor (HO2S), Faulty Rear Heated Oxygen Sensor (HO2S), Rear Heated Oxygen Sensor (HO2S) 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.
