Today on the trail I hit a rut with my rear right tire and my CEL came on. I used my superchips to read them and got P258b Vacuum Pump, and U140c Implausable Right rear wheel speed signal. Anyone have any insight to what I may have done and how to fix? Both my ABS and low traction lights are on as well. Thanks

 

Just go to any parts store and get a rear speed sensor. Can be a pain to change depending on how hard it is for you to get the connector off.

Not sure what to do about the vacuum though.
