Code P-1494 need help
I did a search here and found some info but not enough,so Help if you can please. 1999 GC check engine light came on I pulled code P-1494. It is the Leak Detection Pump pressure switch. I need to know where it is located and how to fix it.

UPDATE: Using the diagram that Joe furnished I found some vacuum lines that were worn out.I replaced these hoses and reset computer,Check engine light is off vehicle runs good,so maybe that fixed it.Thanks

The LDP is located in the left/front corner of the engine compartment below the EVAP canister purge solenoid.
