Review on Denso 234 9040 Fuel Ratio Sensor by Justin Quinones

Like many others I had code P1157 on my 2006 2.4L Accord. Since I was able to save time shipping the part, I was able to get it for 2/3 what I would pay at a local auto parts store and about 1/3 of what I would pay at an auto parts store. Counter! I got the oxygen sensor bushing to swap out and it was worth it. A drop of PB Blaster will help damage the sensor. In the video on Youtube, the exchange looks quite simple. I'm sure that's the case in some cases, but I've had trouble getting a large hand into tight spaces and it was difficult and long to disengage the latch on the old sensor's harness connector. If you're easily frustrated, you can leave the installation to a mechanic.
