Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

POST 1Original post

I have a 2007 997.1 C4S that is throwing a P0441 Code - "Fuel tank ventilation system: Below Limit". Here is Durametric readout. No rough starts No slow starts No Whistle sounds Tried resetting but code came back after 1-2 days. Have a new gas cap on order as a lost cost first attempt at resolution... Any suggestions/thoughts? __________________ This post was auto-generated based upon a question asked on our tech article page here:

POST 2Original post

One very good piece of information on your Durametric readout is that the fault is not currently present. These intermittent faults can be tough to track down but just know that if the gas cap does not fix it, which it most likely will, it is the evap fuel regeneration valve which is located under the intake on the passenger side. Either part number OEM-99711012940, or OEM-99711012900 depending on the year. - Casey
