[@dariusthompson9187]

if my car is having trouble starting after having the code come up could the canister purge valve still be a probable cause?

[@Samm084]

Hey Steve, I put my finger up to the purge valve with hose and electronic controls removed. I felt a slight vacuum. However, when I removed the part and tested it by blowing through it with my own breath, it held tight. Should I replace the valve or look elsewhere for a leak?

My wife has a 2004 Pathfinder and she got a p0455 code (evap gross leak, large evap leak). Took to the dealer, they changed charcoal canister, vent valve, purge valve. Then p0455 code went away, then we got p1456 code (small evap leak). Dealer then changed gas cap, still got p1456 code. Took back to dealer after 1 month, they charged $185 diagnostic fee, said it was stuck vent valve. I researched, bought new fuel tank pressure sensor and vent valve. I installed both, still got p1456 code. On my work day off, I got under car, removed canister (I tested it, good). I noticed rubber hose coming from gas tank to canister was stretchy, so I bought new fuel hose. I cut back a little bit of the purge line rubber hose (it was stretchy). Also I bought new clamps (ones where you use screwdriver to tighten). Installed the new fuel hose (that connects to the canister), 3 new clamps for the 3 hoses that attach to the canister (vent, purge and fuel). Bingo!!! No more codes pop up (no more CEL check engine light). No more evap leaks. Hope this helps somebody.

[@4banger89]

If you experience suction on the purge valve while the engine is running it "DOES NOT" mean the purge valve is bad, as the system will periodically open the valve during operation. It must be disconnected from the electrical source (to ensure the valve should be closed) then you should have no suction. Just wanted to help clarify this.

Hi, I replaced the purge valve and the canister on my 2014 Jeep Grand Cherokee Limited Hemi 5.7. It has code p0455 large leak. When I go to fill the gas tank, as soon as I am done, and try to start the car, it idles and won’t start. It gets stuck on the cranking, then it stops, and then I try again and now it turn on. It only does it when I fill the gas tank.
