Abstract:
Methods and systems are provided for detecting a fuel system leak. While a system vacuum pump is operated to supply vacuum to a vacuum consumption device, air exhausted from the vacuum pump is routed to a fuel system to apply positive pressure thereon. A fuel system leak is identified based on a rate of decay of the pressure applied from the vacuum pump.
