These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

it was still clean and shiny, so it is pretty clear that I somehow managed to pull this loose while I was replacing the AOS.

My other thought was to buy an OBDII-tool and reset the error to see if it reapears, would that be a bad thing to do?

Looking at it earlier, I see a wire running from the sensor to a connector, then up under the intake.

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.

Outcome without a verified action link

hasn't come back yet so I hopeful that this solved the p0343 code.

POST 1 / ORIGINAL POSTEROriginal post

anyone know if pulling the camshaft position sensor (hall sensor) wire loose (or partially loose) would cause a code p0343? I just replaced my AOS and Oil filler pipe, after I started the car back up I almost immediately got the code. since that sensor wire runs up close to the AOS, it is possible I hit it while installing the AOS. Looking at it earlier, I see a wire running from the sensor to a connector, then up under the intake. everything seemed ok, but could not see well enough under the intake to know if it was fully connected.

POST 2Original post

In one word, yes. P0343 Camshaft Position Sensor 1 – Above Limit Potential causes: Check the connector/wiring. Check signal wire from DME control module to CMP sensor for short circuit to B+. This might help: 986-boxster-p0343-camshaft-sensor-code

POST 3 / ORIGINAL POSTEROriginal post

went in to check the wiring and connector to the Camshaft Position sensor. unplugged the harness and checked it, looked ok, reconnected it. traced the wire up behind the J tube where it connects to the AOS. removed the J tube for a better look and immediately saw that the connector was completely pulled out. it was still clean and shiny, so it is pretty clear that I somehow managed to pull this loose while I was replacing the AOS. In any case, plugged it back in and reset the fault codes. hasn't come back yet so I hopeful that this solved the p0343 code. Now I just have to solve the P1126.

POST 4Original post

I had my yearly inspection of my car and they found the P0343. Since it was there last year aswell (without me knowing it) i have 30 days to fix it and bring it back for re-inspection before my car becomes illegal on public roads... argh... Anyhow, I'd like to check for obvious and easy causes before i let a dealer look at it. WHere is the camshaft position sensor located and how do I access it? I guess the mentioned harness is attached to or close to it? My other thought was to buy an OBDII-tool and reset the error to see if it reapears, would that be a bad thing to do? Thanks in advance!
