I have a 2003 Sentra SE-R and am having this exact same problem... I have looked every where on the internet and talked to multiple mechanics, and you seem to be the first person who is having a similar problem. I noticed you posted over 2 years ago. Did you ever find a solution? If you could help me out, I would be very grateful! Thanks in advance!

After replacing all of the Oxygen sensors , the Nissan dealership replaced a computer board and that fixed mey problem . But my earlier visit to dealership said it was oxygen sensor and I replaced each oxygen sensor myself ,and after all that headache , I take it back to them because light is still on , and they tell me that it is a (Emission) computer board that they replaced under warranty . They told me the emission warranty was longer than the std warranty and that I still had 2K emmission warranty left at that time , even though the normal warranty had expired . Hope this helps.

Actually the light went off a few weeks ago all by itself, i was told it will come back on but the car drives fine, no problem and the light do not come on anymore so i guess it must have been air in the fuel tank that i suspected when i bought gas a few days before the light came on. i don't think i have anymore warranty on the vehicle but i will check just to make sure. Thanks

The light went off on its own so i didn't even have to do anything, i am guessing it was air in the gas tank because that happened before but i am still taking the car for a complete tune up next week. I wish i could help you.

Interesting question.... Dealer just replaced my CVT trans in my Murano 2 weeks ago now I am getting 1 O2 Sensor is bad... Anyone else had this problem. Are O2 sensors under the Emissions warrantee?

When the Check Engine Light turns on, it indicates that the engine management computer has detected a malfunctioning fuel or emission component or a system failure. But the most common cause of a "check engine" warning is the oxygen sensor. It can be due to the gradual deterioration of the sensor resulting to the reduction in engine performance. Aside from a failed sensor, other probable reasons the warning light is on are:
faulty spark plugs and wires
clogged fuel injectors
emission problems
short or open circuit in electrical wiring
Better check these other probable causes to be sure.
If the dealer says that the problem lies in the bank 1 oxygen sensor, then have the oxygen sensor in front of the catalytic converter checked. This is mostly due to faulty functioning of the sensor and should be replaced immediately to avoid causing further damage to the catalytic converter.

Thanks for the responses but the light turned off on it's own. This always happens when I buy gas and the gas tank was not properly shut thereby letting in air. My mechanic checked it out and told me what to do the next time I get gas.
