Front O2 Sensor replacement Q?
Recently replaced my front O2 sensor with a universal 4 wire sensor. After getting other work done to the car, I started logging with EvoScan and I am showing a 0 in all LTFT's, O2 Sensor = 0 V and the STFT shows 25 at warmup and 5 when warm and at idle. I have no CEL showing at this time and the car is running rich according to the WB.
Now other mods where done that could cause the rich condition, but I was wondering if the wires could be reversed when I connected the universal sensor.
Thoughts? Anyone connected a universal front sensor and have the right layout for the wires?
THanks.

I've connected a universal O2 sensor. Haven't had any issues with it. The only wires you could possible switch is the 2 black wires, which are interchangeable. They are only heater core wires. Other than that did you accidentally swap the white and blue wires? That's wouldn't be good and you would throw a code right away. BTW this is the sensor I installed. http://www.oxygensensors.com/showpic...0&pkey=1431371
If you're not throwing a code, it might be something else causing your rich condition. My only advise is to log it on Evoscan to see your afrs.
