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.

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

Suggestion

Check the connector and wiring first before replacing -- and as with any fault code clear it and see if it comes back.

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.

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

Outcome without a verified action link

Still not totally clear but I guess I need to poke my head around in there and find it.

POST 1 / ORIGINAL POSTEROriginal post

Hey there, my CEL came on the other day and code P0343 came up as the culprit. I believe this is the passenger side cam sensor that has possibly gone bad? Does anyone have a step by step plan on how to access the sensor and location? Before the CEL came on I have notice that the car does not start as quickly as it use to which I understand is one of the symptoms of a bad cam sensor. My set up is a 2003 996 4S with 39K. Thanks in advance, Richard

POST 2Original post

dyu think that was maybe why the smoke/condensate was obvious the other day in your other posting?

POST 4 / ORIGINAL POSTEROriginal post

"dyu think that was maybe why the smoke/condensate was obvious the other day in your other posting?" This is the first time I have posted my issue on this site...no smoke/condensate as of yet. Richard

POST 5Original post

Who has changed one? I thought I read that the the 3.6 engines were a little easier?

POST 7 / ORIGINAL POSTEROriginal post

Loren can you point me in the right direction on where specifically it's located?

POST 9 / ORIGINAL POSTEROriginal post

In looking at the diagram, the sensor is accessed on top near the intake port and chain box housing. Still not totally clear but I guess I need to poke my head around in there and find it. Thank you, Richard

POST 10Original post

It's pointing/reading the intake cam. It's on the same side of the head that has the scavange pump.
