Diagnostic help
The diagnostic trouble code indicates an electrical fault in the swirl throttle circuit, if there is a mechanical fault, this may manifest itself as a loss of performance above 3500 rpm if the throttle has stuck closed. If the throttle is never closed for a long period, fuel consumption may increase. EGR control is shut off in the event of a fault.
