What O2 Sensor is installed?

So I ordered a replacement O2 sensor. According to the Bosch site, the Base 05 Vibe (VIN 8) takes the Bosch 15309.What arrived is something with a metal plate around it and has the following markings:TOYOTA89465-12710DENSO 004204D09What is in the car is:Toyota89467-12010Denso 025004F26So now I have to wonder:What Bosch part numbers are the above? Google turned up nothing, as well as the Denso or the Bosch site.What O2 sensor IS needed for a base 05Are O2 sensors usually covered under warrenty?

There are two O2 sensors in the Vibe, one in the exhaust manifold and a second between the two catalytic converter stages. according to http://www.car-stuff.com/perfo...=true the Bosch part numbers for O2 sensors are15226 GT before catalyst-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-15289 AWD after catalyst-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-15290 Base 2wd after catalyst-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-15291 GT after catalyst-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-15309 AWD before catalyst-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-15310 Base 2wd before catalystNOTE: That site lists those part numbers for 2003, and doesn't list for any model years since then. Don't expect the O2 sensors changed from year to year, but I can't prove thatI wonder about that 15226, the pic shows a grommet, like the ones that pass through the floor, but the other two "before catalyst" ones don't have the grommet in the middle, wouldn't expect the GT setup to be that different to need a grommet.

thats what I thought the DB listed 15309 for the before cat for base vibe.

Heya 4az,I had a similar issue with my O2 sensor. I ordered a Bosch #15226 to replace my pre-cat sensor, I received the exact Toyota Denso model that was in it, not a Bosch. Was told from Advance Auto that Bosch probably makes the Denso O2 Sensor and that if I have any problems, I could get a different one. I have continually received a P0420 issue since replacing it though I attribute that to the new High Flow Cat and exahust.Joatman, the Before Cat and After Cat O2 sensors for the GT are both under the car directly before and after the cat, not in the exhaust manifold. The Before Cat connects under the shifter and the After Cat connects under the center console.I think the Base only has one coming through the floor where the GT, at least the 2003's have 2 coming up through the floor.Dave
