I'd love some advise on where to look besides the gas cap which I swapped too.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

The CEL on my car came on and I had it checked. I can't remember the code #, but it was minor evap. I looked at my gas cap, and the ring had a lot of cracks in it so I ordered a new one from Pelican. I went to my local shop and had them reset it a couple weeks ago, and it came back on about two days later. I checked the cap, and it was tight. I have refilled with gas a nember of times, and still have the code. Went to have it checked in case it was something new, and still get the minor evap code. Any ideas out there?

You need to get the code number(s), without it anything is a guess.

POST 3Original post

I'll bet it's the same code I've been getting. P0456 Very small leak detected, evap system. I'd love some advise on where to look besides the gas cap which I swapped too.

POST 4Original post

Get inside the engine bay and look for any hoses loose or cracked. Tighten up all emission fittings that are visible. Something I did and found alot of the fittings were loose.

POST 5Original post

I've now gotten P0456 on and off and scheduled a smoke test to figure out where the vacuum leak is BUT now I also just got a new one - P0430 - left bank catalyst Anyone know if they could stem from the same problem?
