So my left o2 sensor wouldnt work so i swaped the harness on each senser and it still says left side lean. So I have a wiring problem. I can trace the red/black wire all the way to the computer. But I have no idea where the power, ground, and the vref run to. Can anybody help?
so I think I know my problem. I have a 02 harness from a 3.8 that I had found in a junkyard thinking they were the same harness. Well the plugs all hookup the same but the wiring is different. I cant find anywhere of a diagram of how to make this o2 harness or anywhere to even buy one.
Iv found some diagrams on veryuseful.com but it shows the hego plug for a 94 but the other diagram is for a 93 which is also different. I need the plug diagram that goes to the engine harness.
I found the O2 sensor harness on Autozone's website recently, so I know it should be on there. I'd try to find it again now, but the site is blocked at my work.
