P0340
P0601
these are the codes im getting, i was told the pcim needs to be flashed or replaced due to it throwing false codes that turn the engine off.
any help is greatly need.
thank you

 

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.
