Hey guys. I keep getting the code p1510h, p2127h and p2138h on my bike. Everyone comes up as throttle position sensor. Is there a way to test it? If not should i just run to Harley and order one? I tried looking it up on the website but couldn’t find it in any of the diagrams even to figure out where it is. Any help is appreciated.

You need the electric diagnostic manual to do the troubleshooting/testing procedure, just buying a new one and hoping that was it is a 50/50 shot. You could have a loose wire, damaged wire, or a bad connector itself, not the actual sensor. That's the correct way to do it.

Ride safe!
