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?
Via Email
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

Hello Clifford,
Thank you for contacting us.
If your twist grip sensor needs to be replaced, you will need to remove your outer primary cover to unplug the sensor and then snake harness through the right side handlebar.
