There is a lot more to the P2074 than two sensors and the pedal. Have you checked for leaks in the CAC system, particularly the cold side CAC tube? You might actually have a problem and not a bad sensor (especially since you have changed the MAF and MAP).
I have an intermittent P2074 on my 2013 but I have a pretty good idea of the culprit. I replaced the cold side cac tube and afterwards, the intermittent code started appearing. The temp sensor in the cac tube does not feel tight, I even replaced it to eliminate a bad o-ring. No luck so I am going to put the original cac tube back on and see if the problem goes away.
I am trying to find the code in my shop manual but for the life of me, I can’t find it. If I do, I’ll post the troubleshooting steps for you.
There is also a TSB for the 2011 and 2012 that you may want to read.
