Are you installing a universal oxygen sensor?

Customer reply replied 6 months ago
I believe so
Chevy Mechanic: AMEDEE, CHEVY TECHNICIAN replied 6 months ago

I dont recommend using those oxygen sensors. They are pain to install.

I can provide you with a wiring diagram if you think it will help.

Other than that, I would have to leave this question open for other experts.

Let me know.

Here is the wiring diagram, it's at the top.

Ask Your Own Chevy Question
Chevy Mechanic: Mike S., Chevy Mechanic replied 6 months ago

I suggest you follow the wires back to where they come from and check what colors they may change to.

Chevy Mechanic: Mike S., Chevy Mechanic replied 6 months ago

Did that answer your question? If so, kindly leave me a positive rating, so I get credit. After all, you have already made the deposit.
If you don't, the deposit you made will just sit there and I won't get my share of it.

No I still don't know what colors go to what. But I wired it up the way I think it goes and the car seems to run fine but check engine light still on
Chevy Mechanic: Mike S., Chevy Mechanic replied 6 months ago

I suggest you follow the wires back to where they come from and check what colors they may change to or where the come from and check the wiring diagram for what color they should be and mark them with some tape wrapped around it and write the color name on the tape.
