IIRC The valve starts to open a little over 2.3 V which is controlled by the engine ECU.
12 Vdc is way too much voltage for the valve.

I thought it was just a solenoid. Anyway, the service manual says to put 12V+ to terminal 4 and ground terminal 6 to test it's function. I do that to hold it open and scrape the valve clean.

In this situation, you better contact your local care workshop.
