Q about placement of wideband A/F sensor - Toyota Yaris Forums

LtNoogie · 01-02-2009, 08:22 PM

I actually had a bung installed between the two cats for my wideband A/F. I was debating whether to spend the extra money to have the muffler shop drop the midpipe so that they could install another bung in the "correct" place in front of the first cat. If the meter is not going to show an appreciable difference, I'll start running the harness into the interior.

Do you still have the stock cats? If so I would consider getting another bung up stream of the cats. If they are high flow aftermarket cats, don't worry about it.

In either case you will probably be OK. It is all relative anyway. No matter where you have the sensor mounted, if your readings change one day out of the blue, you will know something is amiss.
