whoa there chief, lets calm down a bit. i ask cause your previous replies to this thread lead to you thinking a dealership tech (that does not reply on google to diag cars for them) has misdiagnosed this man's problem. between your replies and some others on here if i were the OP and i took the info in this thread for face value i'd remove my car from the shop and go elsewhere, possibly telling the next shop what was said here.

straight up a p2071 code on a crossfire refers to the pcm not getting messages from the skreem module, end of story, i don't care what google says. the correct way to diag that code is by measuring can bus voltages at the pcm.
