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 contain suggestions: 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.

Any advice on what to do here -- hopefully, the only solution isn't to replace all four sensors (though that would be very Schawbisch of Porsche to do).

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.

POST 1 / ORIGINAL POSTEROriginal post

Hi, after 2 years my 2000 986 (98K miles, stock other than ceramic IMS bearing) finally threw a code. I read it first with my CREADER 123 ODBII and recall getting 2-4 distinct codes relating to the O2 sensor. I cleared without writing anything down (hoping it was "just temporary"), but as I a recall, the code descriptions mentioned that is was right or left (or maybe Bank 1 Bank2) and front or back (can't remember which though). After a couple of weeks, it threw engine light again, but my CREADER 123 is now in NOLA: I left it in my Land Rover D2, which my brother borrowed to take to Louisiana for his work with FEMA (guess he's expecting some water crossings). So, I borrowed a friend's (very nice) Aultel, and it only shows one code this second time around, P1119 O2 sensor heating. No mention of Bank 1 or 2 or front or rear, so not really enough info to figure out which sensor(s) (left or right, front or rear) to replace. Any advice on what to do here -- hopefully, the only solution isn't to replace all four sensors (though that would be very Schawbisch of Porsche to do).

P1119 is for the Pre-Cat O2 sensor on bank -2

POST 3Original post

code readers wont say which bank, the code itself will though. Codes will be different for different banks if necessary.

This is a source reference. Confirm exact model applicability in the original material.
