I finished my dpfi to obd1 conversion a while back. Once in a while I get a code 14. Usually I disconnect my obd0-obd1 conversion harness and it goes away. So I guess I'm looking for some kind of short in the EVAC (obd0) / IACV (obd1). The stock dx harness should be A11 (blu/ylw), but if I remember there is two other wires that goto the EVAC / IACV. Any one know what there numbers are to the stock dx harness?

 

on obd0 and obd1 theres just two wires, blue black is one, yel black is the other and it won't necessarily be found at an ecu pin, yel/blk is a power wire that comes from your main relay. Check if for power with a multi meter, if that wire has power and the blue black is at the right pin location then your set

 

thanks... random question. your avatar is that a vw with a b-series? if so i want to see pictures of that ****.

 

i had this same exact problem. i rewired it and fixed the problem...

i tied the yel/blk in with the yel/blk on the fuel injectors. i tied the other wire straight into my conversion harness to the right pin...

 

Stupid IACV. Always giving us trouble.

 

well i tried burn a new eprom for my ecu that would disable the IACV. No go, can't get a good working burn. I'm going to be trouble shooting the issue when i get home. Woopty do! thanks guys

maybe thats your problem?

 

haha.. it worked fine before and just started to act up. i was just thinking of making my own. or just swapping gray plugs to th existing harness. but then the issue would be in the conversion harness.

 

PM me if u want help re-wiring it.
