I actually use 1 on my 2004 commuter car that has worked for over 50k miles. And it passed California smog last month so I know they work for accords.

So as of now its probably the sensor or exhaust leak where it meets the header. I would check the exhaust leak first as it doesnt cost anything rather than buying the sensor.

Have you had the chance to fix it?

Yeah I'm having a problem with with my 02 sensor code coming on. I don't hear a leak but I think I might need to use the stock crush washer cause I'm throwing a code. I don't what to do now? My wife is due in 2 days so the car will have to wait. I does drive fine so I'm not worried just a little frustrated

Yeah I put the 1 that the new exhaust came with. The original 1 was much smaller almost like it fit in the tube itself. Also wondering if the 02 sensor has just had it. The car is 8 years old now and the guy before me had an exhaust on the car so the sensor has been removed and installed a few times.
