Understanding the Control of Renault Megane II 1.6 16V Variable Valve Timing Solenoid

I wanted to ask how it is with the control of the above. solenoid valve, from what I've learned, is controlled by mass. One I do not understand, because after ignition, when I measure with an electronic meter it is 12V, and when I connect the removed solenoid valve, it does not move, when I connect the light bulb, it is not lit either, the plug is 12V, and the solenoid valve does not work, nor the bulb. For my mind this should be how it is and it is clear to me how in the power pressure sensor, through its pins the mass is passed (-) to say some pin in the sagem controller, and here it is like 12V and I can't connect anything - like this is ?

+ 12V is given from UPC, the mass is controlled by the controller. As on the meter you have 12V and the connected bulb does not light up, the poor contact in the plug or the wire has rotted.

Everything is correct, you think well, but probably not quite in your opinion, even if there was a 12 ignition position, the solenoid valve would be open all the time, which means that the control is done otherwise.

+ 12V you have always given (after ignition) and the controller closes the circuit to ground. I don't remember if this valve is normally closed or open. If you connect a light bulb between pin 1 in the plug of this valve and the ground it is to shine. Schemacik
