O2 Sensor Changed, Check Engine Light Still on...? Will it go off?

Hello,

My mothers 2004 Accord had its Check Engine Light come on. She tried the gas cap tightening and that did not work. I had her take it to Autozone and they read the code on the computer. O2 sensor. She bought the Bosch O2 sensor that I changed yesterday.

That was not as easy as I thought.. Jacked up the car and had to remove the pipe from manifold. Not enough room to get socket on 02 sensor. Removed bolts from the exhaust mount and dropped down the front end of entire exhaust. Kept exhaust propped up about 5 inches because Cat sensor was still wired in and at its length limit. Then, vise gripped the flange end while I turned the special socket to remove the O2 sensor. That's tough because of the flexible joint on the pipe, you need to anchor flange before loosening 02 sensor.

Anyway, 02 sensor is in. Drove the car about 25 miles and the light is still on.

Will the light eventually go off by itself? (If the O2 sensor was the problem and is now fixed?) Or, do I have to somehow reset the check engine light? Autozone did state that they would not turn off the light.

Thanks,

Have to get code cleared. I purchased a code reader from Autozone for $39.99 & cleared the code.

Did you get the actual code or did the guy at Autozone just tell your mother which O2 sensor was needed? I ask because the downstream sensor on my Accord ('03 I4) went out last year and initially the guy told me that it was the upstream sensor. I double-checked based on the code when I got home and discovered that he was wrong. For me the CEL went off on its own after I changed the sensor.

Agree. Make sure you change the correct o2 sensor. Autozone informed the o2 downstream sensor was bad. Brought Bosch OEM o2, installed it and CEL went off after the first start.

Just because you get an O2 sensor code doesn't necessarily mean the sensor is bad. You can have a rich or lean fuel conditions, exhaust leaks, shorted wires and other things causing the sensor to turn on the engine light. There are several diffrent O2 sensor codes that will help isolate the cause. You really need to troubleshoot the cause of the problem before throwing parts at it.

First of all. Are you I4 or V6?

Second... why didn't the dude tell you the code? How can he just say o2 sensor? If you're I4, there's 2. And if you're V6, I believe there's 3.

They have different duties. So by him not telling you the code, you might have just spent money on something that you didn't have to change.

You should talk to the Manager.

Anyway, try disconnecting the battery. Wait 10 minutes, and connect it again. That should restart the computer. If the CEL is still on, then you just wasted your money!

This happened to me about 3 weeks ago... I even made a thread about it. The code was P0134

There is (4) O2 sensors on V6. 2 per side.

Its a 4 cylinder.

My mother took the car to Autozone on my recomendation. I would hope that the guy reading the code would be smart enough to sell her the right sensor...(wishfull thinking),,,, Is the Cat sensor the same? If so, would be nice if I could swap the old front sensor provided the front one was good... Or, maybe they are both bad?

Nah bro... the I4 has two O2 sensors, Upstream sensor and Downstream sensor.

The Downstream sensor is on the Catalyic Converter, it serves no other purposes other than emission purposes.

The Upstream sensor 'aka' Primary sensor 'aka' Air/Fuel Ratio sensor is on the bottom of the exhaust manifold.

Did you try disconnecting the battery?

The issue might be the sensor you bought. For one, you cant buy the OEM sensor at Autozone so the Bosch sensor is not OEM. Search around and you will see that some people have had immediate trouble using the Bosch sensor. When I changed mine years ago, I purchased it from a Honda dealer online. It was roughly $65 + ship. Wish I had the part number for u, but again, do a search.

Oh, and driving the car with the new sensor made the CEL disappear.

How much does Bosch sensor cost? Is it upstream or downstream? AFAIK the only sensor that works reliably on Hondas is Denso.

The upstream and downstream sensors are different and not interchangable.
Always remember the parts store guys get paid to sell parts - not to diagnose your problems. And the parts they want to sell are the brand they carry - not always the best one for your car. If you are not well versed on modern car diagnostics they can really take advantage of you. As this sales guy aparently did.
If you kept your old O2 sensor, I would recommend putting it back in and try to get a refund on the Bosh sensor. Tell your story to the store manager if the counter guy baulks.
Car forums like Drive Accord are very useful to research problems before you go parts shopping - not after.

Mothers car is 20 miles away, will disconnect battery provided she can find her radio pin key. My father may have one of those reset computers. Blows me away that Bosch builds a product that us faulty? Still hoping that resetting the computer may solve it.

If it fails I will surely attempt to take it back.

Bosch sells an OEM direct fit for most cars. It isn't so much that the sensors are faulty- just that they don't seem to function quite as well as the Honda OEM sensors in Honda cars (different specs, different tolerances etc.).

Denso makes the OEM sensor for our 7th gens I believe.
