Lasted 4 years and am purchasing it again! (meaning it is great)
I got the P0420 trouble code on my 2009 Rav4, and my mechanic replaced it with an off-brand O2 sensor. However, I got the error again, and he convinced me to replace the catalytic converter, which didn't solve the trouble code.....I purchased this Denso O2 sensor and installed it myself, and it solved the problem for 4 years! I am experiencing the error again after 50,000+ km and am purchasing this sensor again for another 4 years.DON'T CHEAP OUT ON SENSORS, THE CAR WILL HAVE PROBLEMS.......lesson learned!

Honest pricing
This is the downstream sensor and is under the car, not under the hood. Worked well on my 2011 camry and the price is half of what the auto parts store sell them for.

perfect
Fit my 2012 rav4 perfectly. Much cheaper than parts store

Seems like a quality replacement
Ordered this for a 2011 RAV4 with 2ARFE engine - throwing a P0136/P0137 code. Identical fit as the old one. Difficult to say if the OE was Denso or not (was stamped Toyota with no easily identifiable info) but I wouldn't be surprised if it was.Removal was 'interesting' - not so much the sensor itself (I feared it would be seized but came off easy with my 22mm O2 crow foot), but more getting to the connector and disengaging it from the plastic intake manifold without breaking anything. The connection is very solid - had to zap it with electronics cleaner to 'clean' it up a bit. Reassembly was easy - but even connecting it back required slight use of pliers as I couldn't get it to click by hand.Old O2 sensor had a failed heater element which I confirmed by not finding any resistance between pins per service manual. New one has a slightly different head design (more holes it seems).Really competitive price for once on Amazon compared to what I could find elsewhere - came out even as if I had ordered it from Rock Auto ...
