Working on a buddies 2017 570 midsize ranger that starts and idles perfect but the throttle isn't working. When you push the throttle it does nothing. No change in RPMs at all. The check engine light is on, but I am not sure if it related to this issue. I have have checked all of the connections on the electronic throttle from the throttle peddle and on all of the throttle body connections on the engine. The machine has very few hours and is in excellent condition. Any suggestions?
