What are the two white wires on an o2 sensor?
White wires are for the heater – the heater is not polarity sensitive, it’s just a resistive element. The black wire is the sensor output. The gray wire is the sensor return, or ground. Back in the day (old fart mode ON) o2 sensors had simply one output wire and were grounded through the sensor body.
Are there two white wires on the O2 sensor?
The O2 sensor has two white wires, they do not have a polarity, this is why it doesn’t matter which you connect them, as long as both connect to the heater wires. Now you have it connected semi correctly, if you were to connect the ground to the Black wire, you would be replacing your ECU right about now hehe.
What are the colors of the oxygen sensor?

What does 98 mean on an O2 sensor?
Anyhow, 98’s = White is signal, black is ground. Two grey’s are heater circuit. So if using a non-OEM sensor, colors wouldn’t match up, but the black to black, white to grey, and two whites to two grey’s.
Can a non OEM sensor match two greys?
Two grey’s are heater circuit. So if using a non-OEM sensor, colors wouldn’t match up, but the black to black, white to grey, and two whites to two grey’s. Listen carefully when I say never trust the colors them selves and align same color to same color without actually knowing what they actually are.
