p0340 is camshaft position sensor circuit.
p0601 is Internal Control Module Memory Checksum Error

the p0601 points to a pcm memory error, and the fix generally is replacing the pcm and having the new one flashed.

When I thought my ECM went bad I bought a pre-flashed ready to go used ECM from https://www.flashmastersecm.com/pages/about-us. They seem to have good prices and besides the security relearn procedure they are plug and play. Also, if you have a tune obviously you would have to flash that on there as well.
