P015D Ford Code - Oxygen Sensor Delayed Response Lean to Rich Bank 2 Sensor 1
Quick Answer
During a Deceleration Fuel Shut-Off (DFSO) event, the Powertrain Control Module (PCM) monitors the rear heated oxygen sensor (HO2S) signal to determine if the signal is stuck in range. Common causes include Faulty Heated Oxygen Bank 2 Sensor 1, Heated Oxygen Bank 2 Sensor 1 harness is open or shorted, Heated Oxygen Bank 2 Sensor 1 circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
