Yeah, from looking at those spec sheets, it looks like the DY-605 and DY-606 have the same connector and specifications (figure 8). I guess it may have just been some minor manufaturer change by NTK that was enough to warrant a new part number and Ford opted for the updated version sometime during the 1990 production.

After thinking about it, there couldn't have been any operational differences since the EEC really didn't change between those years; the A9L, for example, spanned well before and after '90.

Re: Question About Stock EEC-IV HEGO Sensors / DY-605 vs. DY-606

I cant seem to find the original article that I had reguarding the differences, but I know I had it when I did the MASS AIR conversion. This article stated that the operational specs were the same but one of them had a better heat range and longer life span. I wish I remembered which one it was.

I just saw your reply on the TwEECer board about you remember reading about the difference being quality. I would hope the DY-606 is better quality since it's the newer of the two... and since it cost $10 more through Ford.
