Hi,
This is my first post here and have very little knowledge about car issues. I am trying to get help for my 2000 Honda Accord LX (4-cylinder ULEV) that shows "Check Engine" sign for last couple of weeks. I was given P1149 DTC code by a local repair shop and was told that my car's Air fuel Ratio sensor is dead and need to be replaced. He priced the work at $250 part + $80 labor.

I found another mechanic shop that would replace the sensor for $35 if I bought the part.

I searched Amazon.com and found various Air fuel ratio sensor by Denso (matching my car make, model, trim) that are way cheaper than $250 I was quoted by repair shop. Which one should I buy? Can I rely on amazon's compatability tool? I'm confused but with your help I can avoid being charged excessively for this.

Thanks in advance.

 

Don't rely on Amazon compatibility. Go to one of the Honda parts website

and search the correct part #.
Then search that number.

Just say that if Amazon comes up with this part, Denso 234-4209 Universal Oxygen Sensor.
Check it against another site.

The part # for my 1998 ULEV looks like this on Amazon: Denso 234-9025 Oxygen Sensor (Air and Fuel Ratio Sensor)

 

Your 2000 Accord 4 cylinder ULEV uses Honda part number 36531-PAA-307, which cross-references Denso part number 234-9025 for the air/fuel ratio sensor. On Amazon it is $98.97 right now.

 

Thank you both for quick response. I just placed an order for Denso 234-9025 on Advanced Auto parts website. They have 15% off $112 price and another $25 off $50 coupon being sent next month.

 

And its not too difficult to replace it yourself, too.
You can buy the tool for less than $35, and you get to keep the tool.
