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.
