On Fri night, I cleaned the engine compartmment of my truck like I have many times before. Today, I was out running some errands when these 2 codes popped up at the same time after coming out of a driveway and me hitting the throttle a bit. Can someone help me in what they are? I have a feeling that it might have to do with me doing my cleaning. Still drives fine but it was around town, not even 3 miles away from home. p0643 p0868. I hope it ain't bad, I got 10 more payments on this thing and the warranty goes out in 800 miles (70,000)

Ok, with that link, I got--P0868 Governor Pressure Sensor Volts Too High and P0643 High Voltage At The #2 Sensor Supply Circuit. I'm still lost as to what these apply to or means.
