Ba xr6t Ok so at koeo the output is 1.8 v going by forscan Engine on its .85 volt Now I've just checked what volt is a wireing loom to sensor withulti Meyer and I'm getting 4 wires was 1. 0v 2. 4.95 3. 4.98 4. 5.37 this right?? I wiggled wires yanked them etc didn't change Downt seem correct to me as shouldn't at least one be a feed back wire to pcm so shouldn't have any volts? 😕 Or does it at key on then switchs to a signal wire?
