I am hoping to find some help here. back in august my truck threw a pedal position sensor low input code. replaced pps and code remained. ended up replacing the ecm. January it did the same thing. ecm repaired under warranty. now its has done the same thing again. it's alwaays the same pedal position sensor code. Any ideas here? Thinking about replacing all the wiring harnesses and the pps again out of frustration. not sure what else to do. Wondering if one of the wiring harnesses has and itermittent short or something. My truck is the 2004.5 with the new venture 6 speed and the pedal position sensor under the battery tray. Any ideas as to whats going on here?
