I tried to do a search for this but something wouldn't allow me to view the results.

I have a 2002 Maxima and the service light has turned on twice. I looked it up in the manual and said it was an emission issue, probably because the gas cap wasn't tightened enough. Well, I went ahead and tightened it and the light is still on after driving it for 2 days.

Anyone come across this problem? Is this something I should get checked out?

 

You know, my service light came on too. After I plugged up the computer to check it out, and after I got the work done, they had to clear the codes out. You may just want to take it in cause I'm not sure how to clear out those codes.

 

what work did you get done....my SES light is on and the car is running PERFECT.

 

A couple of weeks ago my check engine light came on and i ignored it for about a month. Then I finally got around to taking it to the Nissan dealership. It turns out that something with my spark plugs broke an engine component and it cost me $700 to fix it. Then 2 days later it came back on so I took it back and they had to "reprogram the chip". But this time, Nissan payed the bill.

 

probably the O2 sensors malfunctioning. i'm getting mine replaced at the dealer

 

a loose gas cap is one of many, many items that can set off the ses. you need to take it to autozone, local garage or nissan dealer. if you go to autzone, they will pull it for free, if not then you will have to get a shop to pull it. most places will not charge a diagnostic fee if you have the repair performed there.

 

Thank you so much guys! I'm going to have my husband take it in to get it checked.

 

I just went to autozone after the dealer told me to leave the car til monday I said "f that".....autozone took 2 minutes to read the code and turns out it is P0171, which their computer said means I am running lean in bank 2 I think she said. In any case, after she read it the SES light is no longer on....the car still runs perfect (the same day the SES came on I replaced the MAF with the updated one and also cleaned the throttle body.)....so as far as I'm concerner all is well now

I was thinking that it could have to do with me using a tank of mid-grade fuel last week for a long trip......though seems wierd that I am running lean since I hear no knocking at all...

 

autozone won't scan codes for free now (at least in my part of SoCal). don't know about central cal though
