P0012 VVT Solenoid no Voltage

Hello,

I have an issue with a P0012. I replaced the Camshaft Position Sensor and the wiring harness since it was faulty, had a bad cable. I also replaced the VVT solenoid twice and the wiring harness as well since it also had a faulty wire. The issue is I get ground, but the yellow wire gets no voltage. I also tried checking the voltage while the plug was connected to the VVT solenoid and no go.

Is there another sensor that activates or is there a sensor that would tell the ECU not to send voltage to the solenoid? Or does someone have a wiring diagram or know what pin is it on the ecu harness?

Also, I did mention the rebuilt head because I did see on OnDemand that there is a plug or a filter on the head that goes to the VVT Solenoid but my did not have one. Maybe the machine shop removed it and did not give it back. I doubt that is even the issue because if the VVT Solenoid is not getting any voltage, it would be irrelevant if it is getting enough oil pressure or not. I did not replace the Timing Chain as well.

 

Apologies, I get code P0010 and P0012. I just ran some test after the car being off a few hours and now I get 6v and then 7v.

 

Thank you for the reply. I may have not been as gentle when I removed the connector from the sensor since the connectors were stuck pretty good. I would get no continuity from the pin to the cable so there was a break in the wire where the wire meets the pin. This happened on both connectors. I did do a continuity check from the new Pin on the side of the VVT Sensor to the Pin on the ECU and I get a proper reading, however I have not been able to do so on the VVT Solenoid connector since I don't know what pin is it on the ECU. I haven been able to get constant readings of 6 volts now on the hot side of the VVT Solenoid wire when connecting the ground to the other wire in the same connector and I also get the same reading if I check positive on the hot wire of the VVT Solenoid and a grounding point on the engine.
