2005 Scion xB upstream o2 sensor change

[@GreyGhost-r4z]

I have a 2006 Scion XB and just replaced both O2 sensors and my mileage has increased 3.56 miles per gallon with city driving. 29.257 mpg in the city. 🎉. I bought the Denso Brand.

That connector is a giant Pain in the rear end

Autozone, O'Reilly and Advance ( local stores) all typically cost more than the selection offered by RockAuto, or AM Autoparts, or TRQ. That said, for important stuff like this even the Bosch has a bad rep..... best to go with Toyota or the brand THEY use ( Denso).....better priced as Denso compared to Toyota. As to the vid......it would have been good to see how the goofy electrical connection was removed.....there is a locking tab involved and I don't recall if you have to push (in) or lift (out) the tab to release.

Yeah I do agree to use what factory uses and guess what this didn’t solve my o2 code haha. Oh yeah the connection you actually have to press a tab and pull the connector to separate, don’t pull the on the wires.
