Question: code P0420 catalytic converter/O2 sensor
Question
2007 Honda Accord @67K miles. Ck Engine light appeared. Took to dealership and diagnostic test showed CODE p0420. WARRANTY 8/80K miles covered the catalytic converter, but was told the warranty DOES NOT COVER THE O2 SENSOR.
Is this TRUE??
Was ALSO TOLD that the O2 sensor was "slightly bent" from "possible" debris from the road hitting it, but its no cause for alarm right now. QUESTION: Do i need to be proactive and go ahead and relace it anyway? If so, then How much will the O2 sensor cost to repair w/labor and all?
PLEASE HELP!!

MasterIf they are replacing the cat converter under warranty I would replace the O2 sensor. The O2 sensor should be covered under warranty unless they are telling you it is damaged by road debris. a bad O2 sensor can cause a P0420 code.There are two O2 sensors front and rear on that car which one have they told you is bent (rear one monitors cat efficiency, front one is more important for fuel trim/control.
Look up Honda North America Customer Service number call them and ask them if they say it is covered you have a stronger argument!Flag ThisLike | 1 person likes this1 -

He DID NOT tell me if it was front or rear either.
QUESTION: Do I need to take it back to them to challenge the information about the warranty?Thank you, I will give them a call to find out.

MasterI too believe the sensor is not a covered component. Federal emissions in 2007 covers only the processor and the catalytic converters. Unfortunate but true.
I find it very unusual and unlikely that the sensor would be damaged by road debris, but I suppose if it's switching as it's supposed to be, there is no cause for concern anyway.
Did they replace the catalytic converter? I didn't really get that from the story.
