Default OCV Solenoid/AVCS Woes.. ECU???

Hey guys, I've had this issue for a good while now,

But I had a new motor installed in my car from a reputable guy, long story short, my passenger side OCV Solenoid is acting REALLY funky.



My passenger side OCV is NOT functioning. I even logged on on RomRaider and yep, Right side OCV sits at 0 mA

I've tried finding out what the issue is and I've narrowed it down to this.... when the vehicle is RUNNING.. there is POWER, but no ground. When the vehicle is OFF.. there is GROUND

Yes I've changed it out with other ones, the problem is still there
Yes I've checked continuity of both wires from connector to harness and its good


Is there a ground side control within the ECU for this?

There was NEVER a point where it had both Ground AND Power.

Each solenoid is grounded via the ECU. Could be a problem there... not sure.

the ground is duty cycled by the ECM. Its to fast to measure with a voltmeter you need an occiliscope to be able to measure the duty cycle.
