I have a 2016 rancher 420 eps, foot shift, efi. Bought it brand new. Only used it hunting seasons back n forth to tree stands. I have gotten the code 23 o2 sensor twice in 30 hours. The first cost me almost $400 at the local dealership. Now I have an o2 sensor I’m going to do myself. Does anyone know how to do this and clear the code? Is it ok to run and just leave the code? If not what will happen? Does anyone know about deleting the o2 sensor? Thank you!
