Good afternoon. This code tells us that one of the three sensors built into the APP does not agree with the other two. It's a fail safe, three sensors work in correlation and must always agree, or else the computer shuts the throttle down.

Since you already replaced the APP, I would be checking the 5V reference circuits going to it. At the APP connector, you should have 5V on pins G, D, and J (white/black, tan, and yellow/black respectively). Is this something you can check?
