Sorry, should have posted the meaning of the codes along with the codes. I did check them, and wasn't intending for someone else to need to look them up for me, I had been asked for them in an earlier post and was just sharing them in case someone knew more in terms of any relationship to potential skreem dysfunction.

Thanks for taking the time to let me know the info about crankshaft/camshaft position sensors; I'll look into it.
