When I did my bars on my 11EGC I had 2 wires flipped in the TBW harness. It uses a redundant system to tell throttle position. If I remember correctly, it uses a 0-5v signal and a 5-0v signal. It uses the 2 values to determine throttle sensor position, so if one goes bad you're not stranded. Mine revved high at first then settled down. If I rolled forward (like canceling cruise) the idle would drop. I had check engine codes like yours. Re-verify your wiring, cut the green plug out if you haven't already. Believe the people here when they say that green plug is the devil's dick, and it's out to F you.

I am following this post closely as I am having issues as well and dealer can't find problem. Go figure. My issue is left handle bar control cuts out and check engine, security light and ABS lights up and nothing on left controller works, totally dead. Sometimes goes back to normal in a couple miles and others it stays out for days, hop on and Fire it up and everything good, ran 300 mile between last hick up. Went out sunday and was out yesterday on way to dealer and 10 mile from dealer cleared. I told them to keep it till they got it right!

Your more than likely gonna have to do away with the green plug one way or another. Or you can ride it out and wait for it to fail. Your call.

What is it with the green plug that fails? When I discovered that I had messed up the wiring when putting the TBW plug back together we checked the green plug at the time and it was all intact and seemed fine.

The fact that you have P1510 and P2138 clearly shows you currently have green TBW issues.

If you don't have heated grips you can cut the extra black wire that comes in the kit, which will afford you more wire "snaking" space inside the bars.

Good Luck! Ride Safe and Ride Often. Rubber Side Down. Over and Out.
