Oh, interesting. It didn't occur to me that the same code would have a radically different meaning depending on model year. My Durametric readout says Motronic 5.2.2, and it is a mechanical throttle body. I think MY2000 (2.7 and 3.2S) was when the change to electronic throttle occurred. It is worth noting that the throttle position sensor might be a totally different thing between mechanical and e-gas.
I didn't think to look in the Bentley manual. In my copy, it shows yet another wording of the codes, and some of them are missorted in the tables so they are easy to miss. It's like people are typing the informational strings in by hand and re-wording them as they go.... I guess I'll wait to see if any code is thrown as I put miles on this week. If not, then I might conclude that Bentley and Durametric are wrong as opposed to Renntech.
