I'm in need of some help from some of you all. Bought a code reader today to hopefully help me find this issue with going into limp mode. I can drive the truck and one day no probs, next day I can't make it out the driveway. I'm thinking I have a loose wire or bad ground somewhere in this deal maybe not I have no clue. While playing with code reader I noticed that acceleration pedal position "d" whatever that is at 19.2 when truck not running, and 85% with truck not running, flat on floor. APP "e" is like 9.4% and top maybe 40%. What is. "D" and "e" and shouldn't those numbers be 0 and 100? Drawing for straws here guys. It threw map sensor code and I replaced it, nothing seems to help it. Any suggestions??? Thanks!
