p2456

i recently reloaded the performance tune from super chips. and ive been getting this code. i tried updating the tuner from there sight and its the same thing.
it doesnt thought this code with the stock tune and goes though the re-gen with no problems.

is there anything else that could cause this besides the programer

still on. i was running a dpf on performance tune. from what super chips told me it leaves no foot print..i guess we'll.

the latest thing is the wrench pops up and i get a tps code with it. the truck is drive able but throttle isnt right. im away again, so my dealer buddy is going to have to take it in for me.
