First CEL in 6 years...
After six years of owning my 996, I got my first CEL. It was Tuesday night in the rain...
Good ol' Durametric said:
P1341
Porsche fault code 174 - Camshaft adjustment bank 1
below limit value
I cleared it, and it's been off for a few days. So, I'm thinking it might just have been a wet connector/plug. But I'll keep an eye on it.
The thing I have to say... the engine picture in the check engine light looks *nothing* like a 996 engine!

Not bad Van.....I love these cars. Even though I recently went thru a motor replacement which was mainly due oil starvation on the track but that is a different topic alllllll together.
I had the 1341 code a few years back. It turned out to be cam actuator.

It may be that... time will tell. And, if it is, it'll be changed.

you're back driving your Porsche again. Did you have a deeper sump with improved baffles when your engine suffered oil starvation?

That has got to be the sexiest oil pan I have ever seen.

So, the error code P1341 came back... This time, I logged some data with Durametric, and in Excel, made this graph.
I'm assuming that, because the bank 1 is materially different than bank 2, that the actuator must be failing. What do you thing? Is this hard to change?

Best case you have an 02+ and super easy swap of actuator (~$120 part accessible after removing muffler). Worst case you have bleed across the rings in the camshaft, not fun fix.
99-01 is different setup and replacement of actuator covered in other threads.

+1 for cam actuator/solinoid. You *SHOULD* be experiencing some power loss over the variocam range. Although this is a fairly straight forward DIY the parts cost is over $1000 from pelican for both the actuator and the solinoid. And, really, you need to go with new parts on this one.

I only have experience with my 02 Boxster. The solenoid and actuator were replaced. The tech said that too often in the past just the solenoid would be replaced and then after bolting the engine together the problem would still be there and due to a worn out actuator.
(My belief is the solenoid fails and causes the actuator to cycle way too much and this wears out the actuator. I note the other bank solenoid and actuator are just fine and they now have 270K miles on them. The passenger bank solenoid/actuator failed at under 250K miles.)
(Also, I spoke with the tech about changing the other side's actuator due to excessive cam rail wear and he said he'd wait and see what the passenger bank looked like. Upon disassembly no appreciable wear so he advised me to leave the other bank alone.)
Anyhow, there is a way to test the solenoid but with a bad solenoid there is no way to test the actuator. To replace the solenoid and then have to go back in to do the actuator just about duplicates the labor for doing the solenoid. The actuator is more expensive than the solenoid and the labor to get to and replace the actuator is a bit more as it requires more work to get it out and get the new one in.
Now in the 996 engine IIRC the solenoid is much easier to get to and replace. Double check this "fact" and if it is right you might consider just doing the solenoid and then seeing if the cam angles for both banks agree. You can always go back and replace the actuator later.

I had the same in mine P1341, I'll never forget that code. Actuator and solenoid was changed at the dealer. Not a pretty $$ amount but had to get it done. Good luck.

You can use the Durametric software to activate the solenoid/actuators for Bank 1 and Bank 2 respectively and read the cam deviation values. An under performing solenoid/actuator would be clearly evident following activation (engine RPM, deviation, engine response). My understanding is the engine must be at full operating temperature. There are quite a few Rennlist threads on this topic, and I would also check/search RennTech.org for the P1341 CEL code and solenoid/actuator replacement. Pelican Parts also has some technical details on this. Good luck!
