Please note that the check engine light once came on last October, and the Porsche technician changed the evaporate canister.

So I erased it and tighten the gas cap for prudence, albeit it seemed fine.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

1999 base, about 100,000 miles (125,000km). New to me since 9 months. I was driving today and check engine light came on. Check the code with an el cheapo reader and is was P0446. The engine was running fine, no lost of power or anything. So I erased it and tighten the gas cap for prudence, albeit it seemed fine. I then drove it for 20 minutes and all was fine. My question is because I erased the code, could this cause any damage or drivability issue? I think not but felt it better asking the experts. Please note that the check engine light once came on last October, and the Porsche technician changed the evaporate canister. Not certain if this is relevant information. Incidentally I read it could also be the gas cap. Where can I get a new one? Any recommendations?

POST 2Original post

P0446 is a problem with the eval canister purge line. Could be the valve or the line itself. Safe to drive with this issue. Here is a good link to read: Code P0446
