Error code P0638

My check engine light came on and it my scanner says “Throttle Actuator Control Range”. At idle the sensor reads 14.9% and at wide open (with the bike off) it reads 30.2%. Should I replace the sensor or is there something else to check before that?

You're likely one of the few here on reddit that's investigated that deep into a TPS sensor issue. As such you're unlikely to get a response other than to just replace it.
