1999 996 C4 Vacuum Leak

Engine

Vehicle Information: Model: Carrera4; Year: 1999; Body Type: Coupe; Total Mileage: 45000;

Hi Joel, My scanner indicated a "Large Vacuum Leak" when the engine light came on. I was wondering if there was one or more sensors that would cause this to display. If I knew where these sensors were located I would have a head start on finding the leak. By the way the light remained off for about 300 miles before indicating the same fault again. Thanks for any help you can give me.Jack
