The "Service Engine Soon" light needs a scan tool retrieve codes stored in the computer in your car. The Service Engine Soon light signifies a problem with the emission system in your car. The evaporative emission system is monitored by the computer in your car and requires an input from the fuel tank sender to test the evap system. So your problems may all be related but requires a scan tool capable of communicating with a Nissan.

I had the same problem and afer many hours at the dealer the end result was the sensor in the tank. I also had a pressure holding problem that was not a part of the guage showing empty however both were fixed and no more problem.

My wife just called me today with the same problem. I have done research and have found the fuel level sensor is the culprit. It appears it is a high fail item in 2005 to 2008 Nissan trucks (Frontiers, Xterras, and Pathfinders) The dealer wants $150 for the part and $380-$520 for labor. Other sites say that you can get the part delivered for $85 at CourtesyNissanparts.com for $85 and the labor is about 2 hours. I have a 2007 Pathfinder and since the repair will cost more than the car note.....I think I'll take a stab at it myself. I'll let you know how it goes and continue to do your research. You never know how much money you can save by knowing the correct info.

You have to replace the fuel level sensor. under the back seat you can remove it from there and replace it. Make sure you replace the O ring also. It will cost you about $120.00 if you do it yourself, if not it will cost you about $400.00 - $600.00 which is crazy. It will take you about 45min to an hour. Once you are done undo the batt cables to reset the computer. I did mine last week and now it work fine.

Okay Autotechpat, sorry to say that you are wrong. I have a 2007 Nissan Pathfinder. I took it to the dealer to check it out - routinely - and find out why the SES light was on. He told me that it was the fuel level sensor and that alone. It does not mean that the emissions are an issue.
Fixit03, what kind of car do you own? Can I do that with my 2007 Nissan Pathfinder SE? I will try it if you say its a go...
