Default Check engine light. AGAIN!!!

About 8 months ago my check engine light came on and I took my car to the dealer. They told me that the "passenger side oxygen exhaust sensor" is defective (bent slightly from when I had my accident) and that the repair would cost me over $220.

First question is:

Is there a possibility that this can be fixed (replaced) by me or do I have to have the dealer do it?

Second question:

Is there a way to just dismiss the error as if nothing is wrong?

Thanks for the advice in advance.

Jay

I can't answer question #1 but in respect to #2, since it is an emissions related problem, even if the check engine light and the diagnostic trouble code was cleared, it would simplyt come back after a period of time if the repair is not done.

EDIT - NefCanuck answered while I was typing my reply.

Hi Jay. Is it possible to do it yourself? Yes, according to your (or your friends) skill level.

Is it possible to "dismiss the error as if nothing is wrong"? The correct answer is no. While you can "dismiss" anything you want, the oxygen sensor serves a vital function in monitoring how the engine is running. If it is not working correctly, odds are neither will your car.

Yes, there are workarounds that people who remove their catalytic converters and perform other unwise/illegal modifications sometimes use, but it does not change the fact that your engine may not work properly and you will likely fail any emissions testing you may have in your State for Motor Vehicle Inspection (if you have one).

Good luck.

So would I have to lift the car in order to replace the part?

I'm not sure where this part is sitting.
bbf2530 would you have an idea?

Hi Jay. Th O2 sensors are located in the exhaust stream, in the area of the catalytic converters. You should be able to access them with ramps, but putting the car on a lift always makes things easier.

Team Ford Parts Online shows the cost of the front back (?) sensor as $56.84 (MSRP of $101.87), and a rear sensor cost of $55.07 (MSRP of $98.69).

You can find them listed here at Team Ford Parts: www.teamfordparts.com/partlocator/index.cfm?action=getJointLocator&siteid=214270 &chapter=&sectionids=2,2496&groupid=24 97&subgroupid=3874&make=23&model=Milan &year=2007&catalogid=2&displayCatalogi d=0

Yours are listed as the "front" and "rear" ones. The "upper" and "lower" are for the 2.3L I-4.

Hope this helps.

Also, I am not sure when your accident was, but have you contacted the Insurance Company (if you filed an Insurance claim) that handled your claim to see if the damaged O2 sensor can be covered as an add-on to the original claim ?

Good luck.

Ok. I'll try talking to my insurance company first but I think the accident was too long ago (almost 1 1/2 years now).

Thank you for all your help.
