Secondly, I noticed that the vacuum line from the intake was very brittle. I would check that before shelling out $80 plus dollars for a new vavle assembly. The vacuum line may be the only problem.

Hope this helps someone!

How do you check the transducer?

I don't know how to check it, really. Just process of elimination;
I put vacuum on the valve and it opened and closed normally, there were no leaks, etc. Since the valve seemed good I just changed the transducer and the CEL never came back.
