Component Details: A good working LNT adsorbs more NOx so that more reductants are required to purge & also it stores more Oxygen. Whereas an inert LNT or a failed LNT there will be very less amount of NOx stored so that once the Regeneration is triggered, the Lambda sensors Cross over will happen immediately. Also, there won’t be any significant Oxygen storage. Circuit Schematic Diagram: NA Component Location and Image:
