Service Engine Soon Light

[duscarter]

I have a 1994 Siverado with the 5.7 in it. My engine light comes on after running for 10 minutes or so. It turns off as soon as you shut down. It is throwing code 32. The intake was pulled last week to replace a leaking gasket, and we cleaned out the EGR valve. It was plugged with exhaust gunk inside the manifold. Got everything cleaned up and put back together. The light still comes on.

 

How can I test the solenoid? The valve itself seems to function. Any other ideas?

I hear you. It runs like a top. I just figured it would be an easy fix.
