🔧 Improved Denso 234-9017 Air Fuel Ratio Sensor for Enhanced Engine Performance Review

I bought model 234-9017 b because another reviewer said it would fit their 05 Civic ex se. The part number on the part did not match the one I removed from my car but they looked the same. I went ahead and installed it. The car started fine, but the next day on the way to work the CEL burned out. During lunch I was able to have an emission certificate made. If CEL comes back soon I will update this review. So far I am very happy with the purchase. I drove the car up the ramps to raise the front

Great price. It is also the same brand used by Honda. I removed my old fuel air sensor and it turned out to be the same - that brand - Denso. Easy to install and you will save $200-$350 if you buy here and install it yourself. The entire installation took about 20-25 minutes. super easy. Watch the video on YouTube. One problem solved.

I opened the hood and removed the upper oxygen sensor with a crescent wrench, and then the lower sensor with a special…

This Denso product is a drop in exchange of the Genuine Honda parts range in price from $240 to $300. With proper installation and code removal, CEL will disappear immediately after a reboot. IIRC if you have a 2001-2003 Civic EX this is the wrong part as they used a different less expensive on/off O2 sensor in the same location than this Denso wide range A/F sensor that Saturation/lean gradient provides . They're not the same - don't buy an O2 sensor and think you're saving all that money when
