Truck just went into Limp Mode??? WTF
So, just changed the power steering pump, started it up and while driving it out of the shop, the little engine light comes on, then a few mins later as i am leaving the parking lot, it goes into Limp mode. Did a system check, everything is fine, light still on, and still in Limp mode. I dicsonnected the batteries for 1 hr, then connected and refired it, still engine light and truck in limp mode. Any thoughts before I grease the Frigg'n dealer for another $100 just to plug in a computer?
