Hello you all, I just joined the forums, so I apologize if this is in the wrong place. I have a 1995 Honda Accord LX coupe, 4-cylinder. It has a little over 258,000 miles on it.

My check engine light recently came on, so I took it to a Meineke, where they told the issue was that my oxygen sensor was bad. The exact wording on the estimate was "Engine codes P0041 O2 Sensor Heater circuit Malfunction and 5-1 SRS Unit Internal Failure"

My father and I had the idea that this seemed like something we could fix ourselves. So I was wondering if anyone could point me in the right direction in regards to where I could purchase a new sensor and how to replace it.

Thank you very much in advance, and let me know if you need any additional information in order to assist me.

 

Help is on the way for you , and this is the correct thread for help questions..Thanks for Joining the HAF..

 

RockAuto Parts Catalog will be the cheapest for the oxygen sensor google "rock auto coupon code" before you buy and enter in the required area when you get to your shopping cart

You will enter your year make and model and look under emissions section and buy your Denso model. Don't buy Bosch as they don't work well with Hondas.

You can rent an oxygen sensor socket from most parts stores and couple that with normally a half-inch drive ratchet. The oxygen sensor should be in your exhaust manifold.

Before you do all this you can put a paperclip into the blue service connector located near the passenger side floor panel and turn the ignition to on and count the number of blinks to confirm you are getting a "code 41" ... there are youtube vids on how to retrieve a honda check engine code for more help

 

Thank you so much, you have been very helpful. This is going to cost me a lot less money than if I had brought to a mechanic.

 

I highly suggest the Denso brand sensor that has the proper electrical connector with it. It will make changing very easy.

You can go to densoaftermarket.com to find the sensor for your accord. I just looked and there appears to be two connectors. One has male pins and the other had female pins. You should be able to verify the connector by unplugging the connector. The sensor is bolted to the exhaust manifold.

Rockauto sells both versions of the denso sensor, so check your sensor before buying.

Here is a video on testing/replacing an o2 sensor. This sensor is in a harder place to change compared to your accord. The process is the same.

 

Good post and good information men.. Thank You!

 

Accord to his car year, his car is obd1 though, PAh. He can't use a scanner.

 

That's what the paper clip is for!
