I bought a cheaper brand which failed after less than 2 months. Couldn’t pass emissions. Replaced with this Denso sensor, code cleared, and passed emissions same day. I would suggest going with the better brand to save yourself the hassle of changing it twice. Perfect fit, easily installed.

This is the same part as the OEM sensor. You can buy a cheaper sensor, but it may or may not correct the error code. This one was well worth $50, considering the auto shop wanted $350 to replace one. It was a bear removing the old one, you definitely should get a 7/8″ O2 sensor (split) socket, and I had to put a pipe on the the ratchet handle to get it break loose. The new one installed easy enough.

This Denso Downstream Oxy Sensor 234-4048 was the perfect replacement part for my 2003 Toyota Highlander 2.4L 4-cyl SUV. I found this part on a couple of specialized parts websites for imports, and then checked Amazon. Sure enough, Amazon was cheaper and easier to order and receive quickly. It’s a hardy looking part with attached cable and connector, looking just like the factory original. It came with a little tube of anti-sieze creme, a nice touch! This cured my problem diagnostic code P0161 for a bad Oxy Sensor Heater Ckt on Bank 2 Sensor 2,(facing passenger side of the engine). I had used a ohmmeter on the heater contacts on the original part, and found the circuit was open, so I was pretty confident this Denso Sensor was going to solve the problem. I also ordered the Ares 3/8 Drive 7/8 Offset wrench on Amazon to allow easy removal and installation of this sensor. Your auto dealer will probably charge over $220 for this job, but it can be done for under $65 with these parts from Amazon, and spending a little time doing your own careful work.

My check engine light came on (2002 Toyota Rav4) and I used a $20 Autel scanner to find out the code P0141. After checking the electrical circuit to the sensor with a multimeter (never used one before), it became obvious that it was the sensor. With the use of the Powerbuilt O2 Sensor Offset puller supplied by Amazon and a breaker bar, I changed out the sensor and all works fine. In all the job took about twenty-five minutes of which about ten minutes was taken breaking off the wire retaining ties. Replaced dome mounted retaining ties through Amazon http://www.amazon.com/gp/product/B00LGKHZ88/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
There are a number of YouTube videos describing how to install an O2 sensor and how to use a cheap multimeter to check the circuit and battery power.
All in all it cost me about $60 to install the new O2 sensor. This particular sensor was for Bank 1, Sensor 2 (downstream after cat converter) replacement. Toyota, with the retainer ties attached offers the identical sensor for $175. Three auto shops I spoke to offered to do the replacement job from between $400 and $695.
If you can, do it yourself you’ll save a lot of money. Just prepare beforehand by checking out Youtube videos on how to put in a sensor and use the multimeter.
Also make sure, after you’ve tested the circuit, you undo the ground lead to the battery terminal. Also don’t let the anti-seize lubricant get on your hands as it will give you nausea later!

I have a 2001 Toyota RAV4 that needed to pass state emissions testing. I had already replaced the upstream A/F sensor (234-9023). I purchased it from here also. I found out the drive pattern needed to get my readiness monitors back. As soon as I hit the mile needed to reset the monitor, my check engine light came on again. This time it was giving code P0420. That indicates either a damaged or leaking exhaust manifold / catalytic converter / exhaust pipe or bad downstream (bank 1 sensor 2) heated O2 sensor. Since the cat(non-universal) was replaced recently and under warranty, I decided to replace the sensor. I bought an Autel OBD2 scanner from here for $19. Great investment, btw. I drove the pattern again. Whipped out my new scanner and this time no CEL, no codes AND my catalytic converter readiness monitor was set. Ready for those state emissions test!
This sensor is an exact OEM replacement for Toyota. Bank 1 Sensor 2 on my RAV4. I read that Denso makes the original part for Toyota. I also read to stay away from Bosch. I also wanted a part I did not have to splice or solder. The sensor came boxed and include anti-seize compound. I am in Amazon Prime and the sensor and scanner were delivered the next day. Nice! I searched for the best deal and found that locally(Autozone,Advanced,O’Reilly), they were trying to charge anywhere from $100 to $150. Online, the best price was about the same as Amazon. I trust Amazon and I have Prime. Since I have a high mileage car and have not tests looming, I think I will replace the other two sensors when I can. Amazon prices are unbeatable. While my CEL light was on throwing P0420 code, I was getting HORRIBLE gas mileage. Roughly 200 miles to a tank of gas. I guess it was in closed loop mode. Anyway, I am one happy camper!

Works as advertised. Cleared my check engine light.
