Are there specific methods to checking hoses for a leak that don't have liquids running through them? I've replaced all the components for that dumb P1443 evap code, canister, both valves. and the light finally went off while i was driving. but now it came back on!! Same code! How could there still be a sensor fault i replaced the valves, so I'm wondering if theres a leak in one of the hoses and its tripping the same code? input is appreciated with this insanely frustrating matter.

yeah so. I opened the hood, and to my suprise, one of the emission hoses going from the canister to the purge valve somehwo got caught around the timing belt, and it tore it to pieces. I'd say it was leaking...lol

 

I'm gonna post this for other people that may run into this problem. Keep in mind this is only for the hose between the canister and the large purge valve. The hose between that purge valve and the smaller black one is the same size on both ends. If you need to get this hose replaced (this is at least my experience at Murray's), you won't be able to find a direct replacement easily, or I don't know if you can at all. You probably can, but to save hassle, what I did was I bought a 3/8" hose for the end that attaches to the canister, and a 1/4" hose for the end that attaches to the purge valve, and then bought a universal (one that accepts up to 3/8") and some 3/8" & 1/4" clamps. You can use the universal/clamps to adapt the two hoses together and then hook the proper ends up to the canister/purge valve. This is the only way I could get it to work because I couldn't just buy a 3/8" hose because it was too big to fit on the purge valve, and then the opposite (having just the 1/4" hose) couldnt stretch to fit over the canister connector.

Hope this helps someone!
