    More than likely. How many miles on your car? I went to 110,000 before I had to replace one. It's possible it's just wiring since only the heater circuit is throwing a code. If you do want to replace the sensor, go here Click Me These guys are great on pricing, and shipping is fast and free.

    Genuine experience carries a lot more credibility than the ability to answer a question.

    you could probably go to a local auto store and get a generic o2 sensor, just wire the power, grounds, and the heater wire and you should be good to go. should be about 70 bucks.

    and do it yourself, unless you can find a mechanic that will do it for free, i had to pay 370 for the whole job when i took mine to a mechanic. :(
