Review on 🔧 Improved Denso 234-9017 Air Fuel Ratio Sensor for Enhanced Engine Performance by Scott Carlile

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 end. I crawled under the front and all I needed was a 7/8 wrench to replace the part. Disconnecting the other end was more work. You have to press the clip on the side and wiggle and pull vigorously to release it. However, it only took about 30 minutes if I counted the time to get it up the ramps and find my 7/8 key, which isn't bad for a first time replacement of this part.
