5Sensor that Car Dealers would use!
By Genchick
Before I purchased, I checked the part number on the manufacturer website. This was intended for my car - 2004 Honda Accord LX. It is Front Sensor that goes before Catalyst. Sensor fitted perfectly and the "Check Engine" light is gone! The price was awesome only $88.64 USD! In Canada it would cost me $270 CAD. Thanks StockWiseAuto for good transaction!

5Perfect Fit for Honda Accord 2005 (EX-L)
By Isah Adeiza
I bought this oxygen sensor (sometime referred as the AFR - Air/Fuel Ratio - Sensor) to replace the front sensor of my Honda Accord 2005 which was indicated by my OBD Scanner. After installing this device, I cleared the trouble code and it kept returning back just as some users have complained. But I soon learnt that the ECU will clear the fault on its own after some number of trouble-free drive sessions. So I let the sensor be and drove my car throughout the next day (about four separate trips). At the end of the day, I scanned the car again and (alas!) the fault code has been reset by the ECU.It is such a perfect replacement part for the Honda Accord 2005 and the merchant had such a wonderful service, timing and packaging. I will gladly recommend it to others.

5Simple
By dazed&confused
This item was a drop in replacement for the factory sensor on my '05 Accord. Length and connectors were identical to the OEM and installation was a breeze.
