[QUOTE="6.0 Tech, post: 1566951, member: 23001"] If wiggling the icp messed with it, I’d guess you’ve got a 5v issue. Wiggle the harness around the icp, see what happens. Your 5v sensors are icp, ebp, map, baro, cam sensor, and app. It will run with everything unplugged, except for the cam sensor. Chase these sensors, particularly the ebp, icp, and cam sensor, as they’re all on the same harness, and the split offs for the ebp and cmp are close to each other, and probably fairly near the icp split off. The app, baro, and map are all on the body harness, but are still using 5v, it would more than likely be a different in on the pcm, but I don’t have a wiring diagram in front of me to verify. The sensors all on the engine will share a 5v pcm pin and a signal return pin, but have different signal pins. Sent from my iPhone using Tapatalk [/QUOTE]
