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.

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

Hello All I was hoping for some advice, My boxster has a misfire and the check engine light comes on. The car still runs and does not stall and will restart when warm if needed. I connected a diagnostic device (iCarsoft) and it said the following: Fault code P0343 - Phase Sensor 1 (Camshaft Hall effect Sensor 1). I then checked You Tube and got stumped! Apparently most people seem to think that the issue is the Impulse Speed sensor. There was only 1 video for the hall sensor, neither of these were having the issues that I was having. Now I do not know whether to change the Impulse/Speed sensor or the Hall sensor. Google AI suggested the hall sensor, which makes sense because the fault caused is mistiming, and check engine light whereas the impulse/speed sensor causes stalling when hot and not restarting until cold. Any help would be appreciated!
