code 23

  1. Honda Rancher 350, 400 & 420
    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...
