I replaced the Hall Effect sensor (phase sensor) on bank 2 and cleared all codes.

So prior to my coil packs failing earlier in the year, there was a very minor and intermittent "lope" when the engine idled - I put this down to a coil, and solved with the replacement 997 units as recommended by Porsche.
Leading evidence: 'Replace hall effect sensor (phase sensor)' (no explicit attributable resolution; this is a reported action or suggestion).

But I'm reading that a failed camshaft phase sensor can also upset the DME from keeping the engine tuned right - I'll be interested to see whether I notice any real difference from what I think is a pretty well running engine.

I followed some Youtube demos on how to test a hall effect sensor (3 wire) using just a multimeter.

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

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.

Hi All
I'm getting one of those occasional "bank 2 camshaft" error codes when I scan my engine. I've cleared it twice, but it comes back. Homework indicates there is a good chance it's just a wiring issue as the hall effect sensors don't fail too often (but they are a cheap replacement @ $150). Bank 2 is driver side at the front - but there's a heap of ancillaries to get through to get to the sensor. I'm wondering if anyone else has had a similar issue and whether there's a tips/tricks?

A little update... Bank 2 is the right side of the engine (looking at it from the back) or RHD driver side. And the sensor is at the gearbox end. I say this as half the material I found had different meanings for "driver side" and what people consider the "front" of the engine.
Pulled the sensor (that's a fun job - so pleased I bought the mechpro low profile ratchet) - make sure you fish out the O ring too. I followed some Youtube demos on how to test a hall effect sensor (3 wire) using just a multimeter. Pretty sure I found my sensor worked only intermittently, which would back up the code being thrown. In any case it's sufficient doubt to warrant purchasing a replacement - it's a standard Bosch unit found across a lot of euro cars and priced around $120 delivered from one of the online shops, so a new one is ordered.

Holy Shit!
I replaced the Hall Effect sensor (phase sensor) on bank 2 and cleared all codes. Took it for a run, and the difference was astonishing...
Clearly this sensor hasn't worked during my ownership, so the car's DME has been managing the engine on a 'safety curve' and holding the VarioCams at a constant setting. Now the car is obviously adjusting the cams through the rev range and I 'feel' like I just scored an extra 50hp low down 2-4k and another 20hp running out to 6k. I'm stoked! Running the scanner over the engine and there are no more error codes.
Woot woot.
