P0023 Fault Code 2009 Cayenne 3.6L V6

So the other day I was driving an noticed that my engine didn't seem right but it was nothing I could put my finger on.  Later when I started it, it was "chugging" very badly but ran fine at higher RPM.  When I got home I plugged in my Durmetric and pulled a P0020 Fault Code: "B Camshaft position-system performance bank 1 No signal/communication, test conditions not completed, fault is currently active and causing a DTC light"

 

I cleared the code and started the engine and it ran better but a subsequent scan showed a P0023 code: "Crankshaft-camshaft position correlation bank 1 sensor b - Value below lower limit, test conditions are not complete, fault is currently active causing a DTC light".

 

Today I replaced both camshaft position sensors and I still get the code and the engine seems to idle worse than before but again smooths out at higher RPM.  I do have decreased performance with it shifting into higher gears sooner than normal as well.

 

Before I throw a crankshaft sensor at the problem I figured I'd see if anyone had any experience with this fault code.  Seems like everything I find online deals with the V8.

 

Thanks

I seem to be having the same issue. P0023 45; did your issue get resolved - what was the root cause?

Welcome to RennTech 

Most likely issues is either a camshaft timing actuator solenoid has a blocked oil passage or has failed completely. A Porsche specific diagnostic tool can test actuate the unit in question to test it for movement.

Was just looking through some old posts and never followed up on this.  My issue was a timing chain issue.  $10k later I had a new timing chain and hydraulic tensioners.  Needless to say I no longer own this vehicle.  Moved on to a 2013 Cayenne S. Much nicer.....
