Code 34 help

I have a 1990 Bronco 5.8efi e4od. I'm getting a 34 trouble code on my obd1 scanner. The book says this is some form of a voltage issue. If anyone could give me a little more info or tell me how to fix it that would be great.

it deals with your egr valve. The sensor that plugs into the top of it is getting too much voltage when the valve is fully closed. Try dissambeling it, cleaning, and then run test again.

It sould not be throwing a CEL from what I remember. Clean it, then try again. Post your results.
