Another p0014/p0024 thread   Im really starting to loose my @*!# over this now.   I have replaced all 4 camshaft position sensors (my z is a GT4) twice now, once with blueprint sensors and now genuine nissan ones however the car is still throwing up these error codes. I have even replaced the crank sensor just encase   has anyone come across this before ? im getting fedup of pulling my hair out now trying to sort the issue   Im thinking would it be something to do with the VVT control
