Any idea why my 2018 2.7 EB would throw the check engine light. It has a canned tuned from SCT 93 OCT, and it threw P0471 which is exhaust pressure range sensor, U0422 invalid data received from control module, and P061A internal module torque performance.

Cleared the codes returned to stock, took it back to Ford. Made up some bull**** story that auto zone told me what codes it threw and they deleted them. Told ford what codes exactly came up and they ran their tool and after three days at the dealership they said they couldn’t find anything.

When I return back to stock codes gone, when I reload tune and drive 30 miles. It comes back.

Tunes been on the truck for 25k and now it pops up? Weird to me.

Any input would be great!

Thanks a bunch y’all.

 

Did you ask your tuner? Not enough info on those codes because I have never came across them.

 

I would contact SCT if it’s one of their canned tunes. You have proven through your own trial and error that it is absolutely the tune and not the truck with the issue.
