Random limp mode
I have a 2011 f150 5.0. It very randomly enters limp mode. Some times with the key turned on to accessory mode. Throws no codes on a regular scanner so I hooked it up to the Ford IDS. it says APP sensor 1 has a fault. I noticed that when it enters limp mode it’s cause that sensor exceeds the correct voltage and jumps to 1-1.2 when it should be not thag high. Like normally it sits at about 0.82 which is in between the range it should . I also noticed that when I move my aftermarket remote start module is when it would spike so I unplugged it and it seemed to be fine. But it just went into limp mode again. My engine runs great and my transmission is good it just has no power and is annoying when it’s in limp mode and I have no idea why. The wires to the APP sensors are still good, like when I move them nothing happens and nothing happens when I move my remote start module since it’s unplugged but it still enters limp mode. Anyone have any suggestions on what to do?
