I have a Maxima 2013. I got "Service engine soon" recently. I showed it to autozone to pull up the reason and they told me it is p014E, O2 sensor slow response,-Rich to lean bank 2 sensor". I wanted to replace the sensor but someone told me to fill the tank with the super grade of gas and to see what happens. The light went out for some days but it came back after my tank got close to empty. Any idea on that? Could the sensors be cleaned? I showed it to Midas and they said it needs to be replaced. They quoted for $400. I found a Denson brand for $100. Can I replace it by myself? If not how much is a labor cost? Midas told me 1 hour around $120.

 

are you under 36,000 if so I would go to the dealer it should be coverered

 

No. I have 51000 on it.

 

Someone told me to use some fuel additive like Lucas. Has anybody used it and do you recommend it?
