I have a Harley-Davidson 2014 street glide and is showing these codes P1510 .2122 and 2138 and the part # that is giving me is 001217-01. I want to know what do I need?
P1510 – ETC limited performance mode
P2122 – TGS 1, low/open
P2138 – TGS correlation error.
Basically, the wiring harness for your twist grip sensor is damaged. Likely have a wire shorted to ground. This causes the motorcycle to go into “limp mode”, or limited performance mode
