I am trying to **** the CEL light on the fam's 93 ATX. I ran the codes the other day and got a 332 and an 02 code. I cleaned the EGR ports and installed an 02. I ran the codes again and I am now getting

214 - CID circuit failure. I can understand that cams seal are BAD. (143K+)
332 - EGR opening not detected. - Um, ok...
335 - DPFE sensor voltage higher or lower than expected.

I am going to double check the connections. I have a spare DPFE sensor I can throw in (not sure if its good). I just think its weird that the 335 shows up now and not in the first set of codes I pulled. What do you all think? Throw in a different DPFE? Would the 335 cause the 332?

Also is the DPFE the little silver box w/2 vac lines and one eletrical connection located on the right of the intake?
