I found 4 wires: Black, Grey, Purple, and White. I have additional upstream sensor, Can I use it as downstream? if can not, which car model its sensor near the aveo sensor&gt;<br>

I ask if the upstream and downstream o2 sensors are similar except the sensor plug or not?
thanks a lot.

Thanks for all of you I had a spare upstream sensor I just changed the plug and install it and it works.
