The wires end to end from the sensor to the pcm and see which wire it is. Use low scale resistance setting on your meter.

Okay I just did a resistance on valve and it is 11 being in spec, I read voltage with key on, on the plug and it is only getting 10- 11 volts. I cleaned the valve and run a fused wire from battery to test valve and it opened and I could blow freely through it, does this mean Im not getting proper volts from pcm?
