The only reason I justify even going there is to get the recall updates and an opinion from the dealer. I assume they know there stuff. I took it there 2 years ago for the other o2 sensor. Anyhow, it will be some time til I go back. I have 210,000 miles on my 2003 Honda Accord EX 4cyl. Thanks.

 

I have the same code P0141. Is there a DIY (pics) on how to do this. So there is something you have to unplug under the passenger seat? I went to advance auto parts and they let me use there computer for free and also said I could borrow the tool for free. The part is roughly $80 as well. I'm assuming I need to lift the car for this.

 

Redskins, what year & version car are YOU dealing with? In 2003 the 2nd O2 sensor wire runs into the cabin before you find the first plug where you can disconnect it from the wiring harness. That's NOT true for all years 1976 thru 2009...

 

Jim. I have an 03 Ex Coupe. Is this something that can be easily done?

 

4-cylinder??

It shouldn't be too hard, but most of us are accustomed to finding a plug on the sensor wire down under the car, near the sensor. Just follow the wire from the sensor & see where it leads...

 

I had a free diagnosis done at Autozone and replaced my secondary O2 sensor (thanks for the excellent DIY post ST Bubba!). Now I need to know how to clear the code to turn off the engine light. How is this done?

Thanks in advance for any help ....

 

Jeljr3, are you introducing another different-year Accord here? What car are you talking about? What was the code number? And did you check the sensor was actually bad?

If the new sensor fixed the problem, the CEL will stop by itself after several days of driving. Depending on what year car, it may be more or less sophisticated in handling the readiness codes & what specific kind of driving is required to clear. 2002 & earlier you can pull the battery cable to clear (have your stereo anti-theft-code).

 

Sorry, it is a 2004 Accord EX 4 cyl. I had it diagnosed on the machine at Autozone.

 

There's about 11 different error codes between the 2 oxygen sensors. Got any code numbers? Even so, many of those errors can be caused by EITHER a bad sensor OR bad wiring in the car. Diagnosis by the machine at AZ is really just the starting point of the diagnosis. You would still want to check the sensor to verify it was actually bad.
