I hope someone can offer some advice here.

My Accord has the Check Engine light on, and when the codes were pulled, this trio of codes all seem to be related.

Can someone advise me on how to troubleshoot this without spending a lot of money? From the code definitions, I am wondering if the high IP line voltage to the sensor could be causing the other 2 codes to trigger, and if that is a likely first step? Or does the fact that all 3 are happening at once mean that the sensor is bad? Any educated guesses out there?

I really appreciate any advice on this.

Thank you,
Dave

First step would be test the electrical current going to the oxygen sensor. Check the wires and maybe replace the sensor themselves

 

First of all, Happy New Year....

Thank you for your speedy reply. Sorry it took me a few days to respond, but the holiday time is a busy one.

Where is that sensor located? I have seen various things online, and so, would like to get a definite answer. I have seen just in front of the CAT and up by the radiator for example. Vast difference in where to look between those.

Can you also tell me what the input voltage should be? I am having trouble finding that information online as well. I assume it could be tested with a multi-meter, if not correct, please let me know.

Thank you very much!

Thank you, Happy new year to you too

i pmed you the information you asked for.

 

My 2003 Accord EXV6 Sedan (163k miles) is pulling P0172 and P0175 codes. I watched a video that suggests replacing the EGR, but I don't want to spend the $75 for new valve without knowing if this is the fix. What was your outcome?

Thanks
