2004 accent 02 sensor

If you invested all the money you've spent on parts, you could have paid for a qualified technician to troubleshoot and repair your problem, and have only paid for parts you needed. Now you want someone who may have no qualifications, and no opportunity to even see the vehicle, to troubleshoot your unresolved problem. LOL

Usually these are located on the exhaust manifold or just below the exhaust manifold and you should be able to see it in the engine bay. On V6 engines there will be one sensor on each of the 2 exhaust banks.
You will probably need to remove the engine cover to see the sensors on your exhaust.

If someone told you to replace these because you got a particular fault code I would be wary. A decent scan tool and basic diagnostics can show if the 02 sensor is working or not. Some faults often blamed on an 02 sensor are not due to faulty sensors.

theres more then one o2 sensor the code its throwing tells you which ones bad the code you have is for bank one

replace the 02 upstream sensor... best solution

Hi

An 02 or Oxygen sensor should only cost about $30 and are readily available, heres one on ebay 02 Sensor

Hope this helps, if not please clarify your fault

When you get any code,it does not tell you anything is wrong or what to replace

You use the code to diagnose the part of the system,that set the code

Most likely cause for an O2 Code, is a vacuum leak,which drives the sensor lean, and it goes out of range. Thus the code is set (Education is the Key )

You have at least two O2 sensors for every single exhaust,four or more for dual exhaust.

Your current code may be a new problem

If there is not the same amount of wires it will not work. I can tell you from past experience they may be cheaper but it will cost you in the long run. Do yourself a favor and get the correct O2 sensor for your car. You don't have to get the O.E. sensor from the dealer, you should be able to find a reasonably priced aftermarket sensor that will plug right in.

Your Accent has rear wiper/washer.. correct? That's where the 3rd wire comes in. They sold you/you bought the wrong pump. Here's the wiring diagrams:

I think this is the O2 sensor - It will run fine but you might notice your gas mileage slipping and will not pass emissions.
