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.

3 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

Would a failing Crank position sensor trigger a CEL even if it was just problematic during warm start? Started to check my earth point cables and have ordered the starter-alternator cable. This will problably solve my slow warm start. Just want to rule out CPS, no CEL on the car which is nice. Will maybe replace starter while I am in there Battery is tested, perfect. Starter runs perfect at cold start, can still be failing. Thanks in advance

My understanding is no, a failing crank position sensor (CPS) won't trigger a CEL. The failure may not let the engine run but it doesn't affect emissions and thus not worthy of a CEL. There may be error codes log, Porsche proprietary ones, but I do not what if any these are. If you are seeing the CEL come on read the codes both active and any pending and post for comment.

POST 3Original post

There should be a list of 996 codes here somewhere - look through them for one related to CPs ... My Benz w204 had failing camshaft ps - which threw a code which I could clear with basic odb reader and then it would come back a few days later. Replaced magnets and all was fine ...
