Denso 234-4153 Oxygen Sensor

Just like the original in fit, finish and function.

With some research and careful review, I was able to swap a faulty O2 sensor for the OEM replacement and clear the code, DIY. Super easy. Make *sure* you are buying the correct sensor.

I replaced both O2 sensors in my 1997 Toyota Land Cruiser. The new one looks exactly like the one from Factory. It works great. No more occasional codes.Note: There was NO improvement in gas mileage. Don't waste your time and money replacing them if you want to increase your gas mileage.

Worked perfectly on my 3rd gen 1999 Toyota 4Runner 3.4l v6 4x4 auto trans. OEM DENSO is the ONLY thing recommended on these trucks as I have heard that other brand sensors can cause problems. Always go with OEM for any sensor. These also came with the gasket that goes between this and your exhaust pipes. I put new sensors in for a fraction of what the dealership would charge, and my truck is running perfect again! Very happy! It should be noted that this is the downstream sensor.

Everything fit perfectly, there was an error PO172, the gasket was completely burnt out, you need to keep an eye on the studs and nuts on the muffler on the O2 mounts, the nuts just burn out and often the studs, DENSO is an excellent product, THANKS TO THE SELLER!!!✌️😁I recommend it to everyone!!!! P.S - the wire of the second sensor (after the catalyst) is a little short; if desired, you can extend it from the old one or stretch it a little

Fixed check engine light, code P0420, 1997 4Runner. This was plug and play essentially for the down stream 02 sensor.

I like it I am happy with the price and products, not too bad, I would like to recommended to everyone

Had a check engine code of P0420 related to the function of the catalytic converter on a 95.5 Tacoma 2.4Ltr 2wd automatic pick up truck. Since the truck had 163,000 miles on it I decided to replace both the up stream and down stream o2 sensors with Denso OEM type sensors to see if that was the problem. After soaking the extremely rusty nuts in solvent, I used an easy out to remove what was left of the nuts. Surprisingly, the mounting studs were still in good condition. I bought some new metric SS nuts from the local hardware store and replaced both sensors. It's been 2 weeks now since clearing the CEL and the code has not returned. Both sensors were perfect fits, came with gaskets, and plugged right into the connectors with no problem. The sensor (234-4153) referenced in this review is the down stream one. The up stream sensor is a 234-4162.I would recommend this product to a friend and it was the best price I could find anywhere.JW
