2007 Foreman 500 blinking gear indicator

I just bought a 2007 Foreman 500 and the gear indicator is blinking 13 times. I looked it up and it said it was the throttle positon sensor. I got online and some people said it’s not as simple as it sounds to change it. The bike runs and shifts GREAT. Couldn’t ask for it to run better. I just don’t like the indicator flashing (OCD I guess). I’ve heard that changing the part doesn’t always fix the problem. (calibrations, leaving battery cable unplugged) Anybody have any issues or pointers I can use to fix the problem? (without costing hundreds of $)
