ok was at school on ALLDATA getting a trouble tree for the 21 code (95 civic hatch z6 w/p28). by the time i got to a computer hooked up to a printer the network was down so i couldnt access the trouble tree again.
so i did the tests i could remember which was solenoid sensor connector to known ground. specs= 14-30 ohms. my reading= 16ohms so i'm within spec. meaning: solenoid good
next test. wiring from ecu(a4) to solenoid connector. my reading= .3ohms so i'm ok once again. now i cant remember what i was supposed to check next. i know trying a different ecu was in there somewhere. is this my next step? i cant remember and ive got a splitting headache from the deisel pad pab that was right next to my lab today. any help is appreciated. thanks

EDIT: code 21 is the ONLY cel i'm throwing too.

 

i also have a honda civic dx hatch white.

 

not sure how that helps me out but bump
