P0140 How to turn off the check engine light?

Hi guys. I got this code p0140. I know what this is and does not seem to change anything in engine’s performance. Now my question is: what is the easy(cheapest) way to get rid off check engine light?

Any help is appreciated.

Thanks pcb! You think the Ultrapower brand will do it for a DD (not a long commute, 50-60 km only) and do you remember the size and where to get that insert you have to use to keep p0420 away?

If you don't have a header and your pre-cat is still good, then you don't have to worry about the anti-fouler trick or the P0420 code.

I would personally just buy the cheapest one.
It's not that big a deal if it craps out, ... you just throw a code.


These are the nonfoulers.





They have a premade version now so you don't have to drill it out (which is a PITA.)

Those O2 sensors can be seized up pretty good and a PITA to remove.

You can cut the wires off the old one and put a deep socket on it.

You'll need to use a wrench to install the new one though.

Thank you guys for your suggestions. I know is a PITA to remove that sensor because I've done it once, years ago and now I guess it's time to have fun again 🙂.
