Truck would not remote start after work. Thought it was odd. When I started it from the inside the check engine light was on. 2900 miles so far, hopefully it’s something simple. Will probably try the dealership Friday.
HUH...Don't understand How a rear diff would set an engine code???? Might want a new dealer, they could be jerking you around.My check engine light came on at 1000 miles. Went to dealer and the code was a bad sensor on the rear differential. Service advisor said they were backed up and I wasn’t going to hurt the truck so I have kept driving it. Will have it replaced later.
