oxygen censor question.

Just this morning as I was turning on my car before heading out to work, my check engine light came on. Later that afternoon I took my car to an autozine for a quick check. Turns out its my oxygen censors......??any idea the cost of this? Any other info?


Thanks.

I believe you have two sensors, one in the front and the other in the rear. They generally cost around $70 bucks each. Did the folks at autozone tell you which one is bad. If it were me I would replace it with a Bosch sensor and not some cheaper version found on Ebay.

Yes, one upstream and one downstream.




Prices do vary but OEM is around $130 each online and there is a difference in wire length as you can see in the picture. "Bosch" would be my first choice versus generic.
