    Honda Accord 2003 (Sedan/4Cyln)- O2 Sensor light on
    Hi,
    I am driving a 2003 Honda Accord, Sedan, 4 cylinder. I have put on apprx. 28K miles which is not too much for an '03 year model. A week ago, one of the light was on. I did go to check at one Honda Car Dealer and the guy told me it was the 02 Sensor needed to be replaced. And he told me it will cost $500. I am not sure how important the 02 sensor is or whether I really need to replace it immediately.

    1) What could go wrong if I don't replace it in time?
    2)or what possibly endangers me while I am driving with this condition?

    Anyone can help me to answer these questions. If I need to replace it then
    3) Where I can get the lowest cost for the O2 Sensor replacement?
    4) And is the $500 estimation reasonable?

    Thank you,

    Nqt--

    I can't answer your questions, but just a word of warning:

    Original parts are ALWAYS more expensive! Sometimes up to 2x the price, minimum!
