Engine Codes - P0401 / P0299?

[miller-ryan]

I installed a Banks RAM Air on my 21 HO and am now getting check engine codes.

I'm getting P0401 and P0299.

Any Idea what I can do to eliminate the issue?

I have called Banks, and they said we don't have those codes not or a problem.

Did you plug in all the connectors?

Is the truck tuned?

Has it been to the stealership lately?

No, and no.

I am trying to decide if I want to delete or emissions on tuning and who's tunes.

You most likely have an intake air leak at the new intake horn; also, check the MAP sensor is plugged in.

See attached troubleshooting information for your codes.

I installed an S&B and got an "Excessive EGR Flow" code on my 21' SO.

S&B sent me an updated tube with the MAF in a Different place.

No more problems, but I also don't have a working EGR anymore.

Try the troubleshooting PDFs that AKBob sent.
