About 6 months ago I was driving down the hiway and truck went into "limp" mode. So i Ran the codes came back throttle body sensor and pedal position sensor so got those changed out. About 3-4 months ago my knock sensor code came on and got those changed out. Now about a month ago the pedal position sensor code trips again so I changed it out about a week ago, well now it is pulling the code again and keeps throwing my truck into "limp" mode randomly. Has anyone else had this problem? If so what was your fix for it? I am sure it is not messing up that sensor that fast so I am not sure what else would be tripping this irritating code!!!
