CEL p0440 back on after gas cap replacement

[Ldub]

I think that 'whatzitznutz' is called the purge valve solenoid.

The little research I did though indicates that it could still be (in order of likelihood):

non-OEM gas cap
Cracked evap canister
split hose or leaky connection
purge valve solenoid
wiring harness or bad connection

I still get the P0442 code on the Amigo regularly (but only when the fuel drops below 1/2 tank). I'm running an aftermarket gas cap but should probably switch back to the OEM since the replacement didn't fix the problem.

The US.RV shop manual has pages & pages on the subject. It just hasn't bothered me enough to try & chase down that gremlin yet.

My Amigo has had the ck engine light (maybe it's a Calvin Klein sublim ad) on since about 1 day after I brought it home from the used car lot where I found her. Had the code read, & same-same.
Pulled tha ol' switcheroo VX-Amigo re: gas cap...no change...

The only thing that makes the light go off for any appreciable amount of time is -15 degF & lower. Mebbe that's just too dam cold for tha light...to emit.....

But that kajigger what Gill wuz talk'n about sounds like a promising next step...

Mine has been throwing p0440 for almost 6 years, about once a week or so. I just reset it with the ol scangage and not worry about it. Every once in a while I get the 441, which I believe is in the same category.

Mebbe I missed the post or sump'n. What year did you get? Does it have the 3.2L? Stick or Auto?

Mine's a '99 with the 3.2L 5spd. Previous owner upgraded to leather interior, added the temp/compass cluster on the ceiling & added the stock cruise control from a donor. It has the hard top but I need to get a rag top for it for summer use (I'd also like to get the hard top LineX'd since it's faded - cheap option for me now since Boy is working at LineX this summer & gets it done for cost of materials). I put on a 3" lift but haven't upgraded the tires yet so it's kinda funny lookin at the moment.
