While I can't offer a solution, I can offer sympathy since I'm in the same boat. '12 Tri Glide and was throwing the 1510 (among others) code so I thought it was the twist grip sensor so went to HD and bought the extended version and took the bars off and ran the new one. No change. Trike is in limp mode with CE light and blinking cruise light (indicating no throttle). I can't get it out of limp mode either. I have an extra set of hand controls off my old ultra along with two other twist grip sensors (short version) and can plug them in and still no change. I have removed the tank and checked wiring, have removed the a/c and checked and cleaned and greased the connections to no avail.
According to the electrical service manual, the 2127 code is the one to diagnose first and the first step in that diagnosis is to connect a break out box to the ecm.
So, I guess for me it's off to the dealer with credit card and ky in hand.
Good luck on yours.

Might be a better idea to start your own thread on it . Be a little more specific with your question , what kind of bike ( 15 Street Glide S ) , any mods from stock and exactly what errors codes came up .
Did you recently do any work on the bars ?
Did this problem just appear ?
Off hand I can think of , double check your connections for your handle bars ( TGS ) and the connection at the TPS . Check for damaged wiring , pins in the connector itself etc . You can use an electrical Contact Cleaner as well to clean up any corrosion too .

I'm going through this same thing now with the codes you've described. Recently purchased a 2011 Street Glide with 5,995 miles. This bike is in immaculate condition. Put about 300 miles on it and then it left me stranded. Went into limp mode and had to have it towed in. Previous owner had mini apes installed. Code 2138 led me to the wiring inside the bars. Someone on this forum stated to fix this code and all the others will go away. Pulled the wires out of the bars and found that the green connector was destroyed. Along with several wires with the covers torn. Whoever did this job needs to keep their paws off of bar installations. Purchased the CVO throttle wire harness, repaired all the shredded wires and put it all back together. Started it up and had no codes and runs like normal. Pulled the front brake lever and had no brake light. These Harley connectors are trash. Removed the plug and found that for my red wire with yellow stripe (brake light), had the pin pushed out. I'll replace with a new pin and see if it stays in place. If not then I will replace the 12 pin connector. Code 2138.
