🚀 Enhance Performance with Denso 234-4574 Oxygen Sensor Review

Great buy, just like the original, can't be beat for the price, go to the dealer, they charge twice the price, I recommend!

It's very good. It works very well with my 2016 Honda Accord EXL. You will need to attach a piece of rubber around the power cord to keep it in place. See photo of the original. After a reset, the check engine light no longer lights up. Better fuel economy. It's worth the price.

Helped fix a friend's 13 Honda Accord by throwing away the downstream oxygen sensor code. Worked like a charm and installed in minutes. The only thing to note is that the original had a rubber grommet attached to the mount to keep the wire out of the way, instead I had to tie it to the mount. Actually not a big deal.

I had a dreaded P0420 code. Bought this bottom sensor for my 2010 Honda CR-V along with a $25 sensor hookup kit. I sprayed the sensor with rust, everything is fine. The connection is a little tricky, but I finally figured out how to get there. Installation was quick and when I started the car the code was gone! The old sensor was white I think from 10 years of heat so it must have been bad.

I bought this to replace the downstream oxygen sensor on my 2011 Honda CRV. The check engine light came and went for several months. Eventually I asked AutoZone to check the code and code P0420 popped up indicating that the catalytic system efficiency was below threshold. Catalyst failure made no sense to me on a 7-8 year old Honda with 92,000 miles. The forums have stated that replacing the O2 sensor is worth trying, hundreds less than replacing the cat of course. Be careful not to get it on…
