There is a tube that comes from the bottom of that sensor and goes to the passenger side exhaust manifold. Take that one off and clean it out. Chances are it is rotted and has a hole in it. What month was your '97 made? If it is a late '97 I have the pics and part #'s of the tube you need in my pics in sig.
That is where I would start first. Also the sensor may be bad too.

Do you still use the back pressure valve or is it disabled? If you dont use it you can just get a simulator to plug into the harness instead of the sensor. Any other codes besides the 3 for the EBP sensor? Ive never seen either the sensor or the valve set a CEL.
