Explicit resolution reports before identified causes, performed actions and suggestions. 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.

Discussions that suspect a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suspected cause
It would have thrown a code in the first few minutes if an issue was still present.

Ignored for a week or so but then I had problems with the MAF so I had to change it along with the spark plugs, air filter, etc and reset the code.

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 1 / ORIGINAL POSTEROriginal post

Hi there, I have a 2001 Boxster w/ 82K miles. I had a P0430 code (cats). Ignored for a week or so but then I had problems with the MAF so I had to change it along with the spark plugs, air filter, etc and reset the code. Since then, I drove the car 250 miles or so... and still no CEL!:-))) My question is: How often does the ECU retests the engine? I would assume that it is an ongoing process and if truly I had a cat converter problem, the CEL should have been back by now, right? Am I off? Or is it simply a matter of time? Thanks Bob

POST 3 / ORIGINAL POSTEROriginal post

Thanks for the reply Paul. That is really good news given the cost of a new cat converter. I appreciate the reply. Bob
