Still getting 41 and 14 no matter what I do.. I know that the blue/black wire on the AICV is sensor and the yell/black wire is ground however I did notice that on the civic harness when i was doing the wiring that those two wires were yel/black. I tried switching them around however the code is still there.. Any suggestions.

Also the O2 sensor is really going to make me lose my hair. It comes with the the green and white wire on the right and left respectively and the two black wires on the bottom. I know that the white wire is sensor signal and the green is sensor ground. However why am I still getting a 41 code.. I even unpluged it completely and started up the engine but I still only get a 41 code and not one for the o2 sensor.. Any help will be greatly appreciated, I should have all the work done within 2 weeks for some road testing...

I will also be taking some more pictures this weekend of my dirty engine bay for anyone else that has anymore questions...

 

Are you talking about the IAC??? the thing with the two coolent lines hooked up with some black plastic on it?Make sure the BLK/BLU wire goes to ecu pin A9
and A25 should be ground for the YEL/BLK. Make sure you test the wires with a volt meter see if they are auctually connected and so you know your wiring is good. If that doesnt work Double check the ecu pin, And lastly take the IAC appart and clean it out it may be just dirty my friends 00si had that prob. Your o2 sensor may be bad im not exacty sure which wire is which i taped mine up already. Check the harness on your old motor see what colors they are.

 

I am talking about whatever code 14 is. AICV.. I think its located on the front of the intake mani right after the fuel rail if you are facing the front of the car looking in..

I will have to check the wires and see what the current is but the funny thing is when I reset the ECU and unpluged the o2 sensor completely the CEL 14 would disappear and only code 41 remained.. But you are right I may have to take it apart and try to clean it out and see if that is the problem...

And I am thinking that the o2 sensor might be bad as well, which would suck because I bought it off of someone online. But the wires are the exact same as it was on my old car..

 

code 41 is for the o2 heater circuit. The sensor is fine you just need to make sure the heater part is working. The 2 black wires are the heater. Unplugging the o2 will not make a code 14 dissappear. Are you sure your not confusing the 2.

 

No not saying that it should have disappeared, but in unplugging the ECU shouldnt I have gotten a code for the o2 since the ECU couldnt see it.?? I just think I need to take a complete relook at the o2 wiring and then let you guys know what is up from there..
