Default Does CEL turn off by itslef?

I have a code for a faulty O2 sensor. My question is if i replace the sensor will the light turn off by itself?

It will turn off by itself after 40 warm up cycles. Just disconnect battery and it will clear

What is a "warm up cycle"?

How long should the battery be disconnected? And will the seat memory settings be lost?

Is a "warm Up cycle" = turning engine on?

I would like not to loose the settings.

It shouldn't take that long. Mine only took about 8 miles down the road to turn off.

Hi CL. I'm very excited cause i just ordered new wheels that should be coming on Monday... TSW 20's. I also ordered d2 rs coil overs that will come next week too. I'll post pictures as soon as I install everything. But my concern right now is that my cel is on as well. I was told to disconnect battery and the light did come off, but came back on later. My vsc and abs light also came on after i lowered my car. Can anyone please help me with this

Sounds like you broke the ABS line.

Cant say anything abt the vsc or abs, but go to an autozone or auto shop and they should be able to diagnose which O2 sensor it is. It also may be related to worn spark plugs so have that checked too. Your shop should then clear the CEL (not the battery way). Then you have to do a test drive for about 30-40 miles before it officially clears to determine ur car has been cured.
