Had this code for a while now on the 03 Lancer. Never bothered doing anything but emission testing is soon and a CEL is Fail on the spot.
The Lancer is powered by a 2.0L SOHC motor with maybe 110k. CEL is on, i noticed a little stumbling at idle once in a blue moon, might be related or not.
Cleared the fault, it comes back after a few drive cycles so obviously its a real fault. I did the cheap and easy route, got a new gas cap. Carquest branded, made in the USA from AAP. At the same time i removed and tested the "evap purge solenoid valve" the one in the engine bay. Applied 12v and heard/felt a click, tested the resistance it was 33ohms (spec is 30-34ohms @ 68F).
Cleared the fault after new cap and confirmed one valve is good. Drove 2-3 drive cycles and back again P0456.
Next up should be checking the valve at the canister and other lines near the canister.
Any other suggestions? Every time i've had a evap related fault it was always the engine bay valve, the valve would be stuck open or closed. This is my first out of like 9 cars i'ved messed with not to need a evap purge solenoid or a completely broken charcoal canister.
Is there a cheap DIY smoke machine method i can do.
