My check engine light is on and I have changed both o2 senors any help on why it wont turn off? How long do I leave battery unhooked to reset car?

What’s the code #?
Not every check engine is an o2 sensor
Battery disconnected for 35 min will do it
But if it’s an hard failure you can disconnect the battery for a month and it will come right back

Good luck
Let us know
