Ok might be a dumb question but I have one.... ok I have a 95 civic coupe with a greddy 15g turbo I just installed a AEM Wideband so now my CEL is on.... so what do I need to hook up or do to make that go away?

 

Ok I have been searching and searching and confused on where to run the white wire.... half are saying D14 and the other half are saying D10... where does the white wire go???? Some input with reason please. And will this turn the CEL off when it is hooked up correctly? Please any help..

 

What ECU/engine management system are you using? And what are you looking to get out of hooking up the wideband O2? Are you looking to monitor AFR's or do you want it to run with the ECU?

What is the CEL for? I will assume that you have checked it and it is O2 related. That being said, is it for the O2 heater circuit or the sensor circuit?

The stock O2 sensor signal pin is D14, however without a modified/chipped and tuned ECU, the wideband output from the sensor will not read properly. If you are looking to use the narrow band signal through the stock ECU that would be pin D14. D10 is a secondary input that can be used to read wideband signals, again, only if you have the engine management, or tuning software, set up for it to do so.

 

D10 is the eld signal and will throw a code ... Check your codes

 

Itll throw a code if you dont have an ecu that can disable the eld and use d10 as an o2 input
