91 sidekick. Mpi 4dr 4x4 1.6
New here. Need help! Super stuck. Been a tryn figure this out goin on 2yrs now. Dropped the 5v ref on my tps. Grey red. Can’t find any wiring issues at all. Load tested. Tested for stray vol so on. Must have missed something but no idea what. Did find the maf was sending 7.6 back on the sensor wire. But unplugged it and still lost my ref. Falls to about 2.5ish. Then takes a week or two if I’m lucky for it too come back?♂️ And that’s completely unhooked from the harness testing it off gator clips to battery. Did just see that if I only put power to the ecu I would get 12+ v on my grey red wire. Even on an older computer that’s shot. It won’t go higher that .08v.
