Not much traffic on some of the other forums so thought I would post here to see if anyone can help.

Have a 2000 986 2.7 tiptronic. Getting P1340. From what I have been able to find I should get 5v between pins 1 & 3 with key on and 0v between 2 & 3 with the key off.

With key on I get 5v to pin 1 & 3 and 12v to pin 2 & 3

At this point I am actually hoping it is the dme and not wiring. The car does start & run, although it idles rough. Once I get it out it drives fine with the rough idle. I shouldn't see any voltage between pins 2 & 3 with the key on or off right?
