    P0441 and purge solenoid connections

    Hey guys, I have a 97 Corvette that I modded about a year ago. I keep getting a p0441-EVAP System No Flow During Purge code. I was digging around the purge solenoid and valve a couple of connections that look like they should be connected to something. Anyone have an idea where these need to go?

    Thanks

    I may be getting the names of the parts mixed up. i apologize for that. In this pic, you can see the purge valve to the left of the pic and to the right you can see another blue connector. that is the piece I have pictured in the first pic.

    I have looked, but I haven't sen anything. Guess I'll take another look and see. I don't remember having any extra hoses left over after the mods either. I'll fdig in their and see what I find. If you look, there are two connections. The second is the rubber 90 deg hose on the bottom of it. ANy thougths on that? Thanks for the help. I have been chasing this for a while now.

    the 90 degree hose goes nowhere. the hose that comes from rear of vehicle from the evap canister should run next to your fuel lines comming from fuel tank look where fuel lines come into engine compartment and evap hose should be wrignt there too. not positive on corvette model but almost all gm vehicles i have worked on the fuel lines and evap lines all run together from rear of vehicle.

    I found that line from the purge, but it tees into another connection on the valve as it continues over to the solenoid. There is still teh connection open on the other side of the valve.

    well, it appears there are no other connections to this valve. Only the one that tees into the main hose from the canister. Wow, they sure look like something should be there.

    I did however find that a hose connecting to the solenoid was disconnected somehow. that is probably the cause of the p0441 code. We'll see I guess

    Thanks for the help
