2015 FLHTCU How do you reset the TPS? Or do I even need to do this?
The bike is equipped with Nitrous and we've had throttle issues lately with
Codes
P0120 TPS range error
P0123 TPS high-open
P0122
P0222
577
Any help would be appreciated

 

Sounds like a possible TPS sensor gone bad OR a wire leading to the injector is failing/failed.
