Can you back out a little on the photos, I can not see where you are.
For the 5VDC test put your red (+) probe on any of the red X points and the black (-) probe on any of the purple X points in the diagram below and turn on the key:

The EVP is not in the coil area. It is on top of the EGR valve.

I do not think you had an electrical error code for the EVR and the EVR is what is in the photos.
If you have a bad wire going to the EVP then yes it could cause the error code as you did have an error in that electrical test.
But the EVP has a Orange wire with a white stripe for 5VDC power, Black wire with a white stripe for ground return and a Brown wire with a light green stripe for its information return to pin #27 of the computer.
I think you are getting the EVR solenoid & the EVP sensor mixed up.
The electrical test is the KOEO test.
