P128E MINI Code - Nitrogen Oxide Sensor Oxygen Sensor Signal After Regeneration Dynamics Binary Dynamic Response Too Low
Quick Answer
The Engine Control Module (ECM) monitors the Nitrogen Oxide (NOx) Sensor. Common causes include Faulty Nitrogen Oxide (NOx) Sensor, Nitrogen Oxide (NOx) Sensor harness is open or shorted, Nitrogen Oxide (NOx) Sensor 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.
