Nissan Sentra 2005 Service engine light, gas overflow

13 years old, what service history?

hi, dear friend, this is an obd2 trouble code table. it can help you understand the meaning of code.
The best way to fix a P1456 error (small evap. leak) on your Nissan is to have a "smoke machine" test done on it. This machine is hooked up to your car and pushes smoke throught the evap. system. The smoke will shoot out of the leak and indicate its precise location. You can also try getting a new gas cap and make sure that it clicks 3 times when you close it after filling your tank. Also, NEVER leave your car running when your fueling up as this can cause your "service engine soon" light to come on. The best choice however is doing the smoke test as this will elimiate any guess as to the location of the leak. Nissan dealers can perform this smoke machine test for you for about $90.00 and can save you alot of money by pin-pointing the leak so you don't keep buying parts you don't need.

Take your car to a local parts store, they will read the engine code for you for free. They will also offer possible actions  fix it and parts it will take. Be careful out there.  

Just fixed my wife’s 2005 Nissan sentra for the same problem, the service engine light was on and when I tried to put gas in the tank it would gurgle up on me and come out. After doing a little research on line (I love the web) and talking to the dealership it ended up being the vent control valve. Newer model cars have pressurized gas tank, this valve closes when you start the car to pressurize the system and opens when you shut it off to vent the system, and if stuck closed the system will not vent wile pumping gas causing it to come back up the pipe. Nissan has had a lot of problems with this valve and since have redesigned it.
The valve is located just to the rear of the driver’s side back tire, you will have to remove the plastic shield to get at it and if you remove the back tire it makes the job much easier. It looks like a tube with an electrical connection on the side at the top and the hose from the gas tank on the same side at the bottom. It is attached to a black box I thank they call it the carbon box. Remove the valve by turning it counterclockwise about ¼ to ½ turn and pull it out. Remove the electrical connection then the hoes that leads to the gas tank. If you look inside the holes you will see a plunger and a spring, if the plunger is down and seated it means it is stuck closed. If you’re not sure you can do what I did and try to plow thru it if you cant you have your answer it’s closed. I had to go to the dealer for the part and they soaked me for $152.00 but better that then paying for them to do this simple job. To reinstall the new unit just reverse the directions. Once I had the part out I disconnected the battery in the hopes it would reset the check engine light and after the job was done I reconnected the battery and everything was fine. I think it is a pretty simple job and if I can do it anyone can, good luck.

good day Sir, try to check if the oil level is to much maybe thats the cause of the overflowing i hope this tips will help you.

You shouldnt be changing your plugs that often. You probably have a short with your service light. Have an electrician check it out.

IF THERE IS A LOT OF WATER COMING OUT OF THE EXHAUST, AND THE COOLANT LEVEL IS LOW, THEN YOU HAVE A BROKEN HEAD GASKET. ANOTHER SIGN OF A BROKEN HEAD GASKET IS WATER SHOOTING OUT OF THE OVERFLOW BOTTLE WHILE IT IS UNCAPPED. CHECK WHEN IT IS RUNNING COLD. HOPE THIS ANSWERS YOUR QUESTION. GOOD LUCK. THANK YOU FOR AN HONEST RATING AND FOR USING FIX-YA.

did you receive the Nissan Service and Maintenance Guide, when you purchased your vehicle? if not go to www.nissanusa.com/pdf/techpubs/2006/2006_N_SMG.pdf

to get the 2006 manual it should be the same, or go to www.nissanusa.com use the "for owners" tab top right and you can download your specfic mileage service

if the car is running fine give it no concern. for many vehicles the check-engine light comes on and won't go off. most of the time people take them to the shop. if the guy is honest he will tell you that all he had to do was reset the computer. but most of the time it will come back on after you drive it about a hunderd miles.
as long as its running fine, leave it alone. it's like my grandpaw said if it aint broke don't fix it. good-luck ray

it could be that your fuel pump could be weak. or that it's in the electrical circuit of your fuel system. what that means is that the sensors that help read the performance of your fuel system could be malfunctioning. this would involve the O2(oxygen) the TPS(throttle position sensor. or it could be the fuel pressure regulater. you could probably go to a small garage and have scan done cheaper than if you take it to a dealership.hope this helps please rate this ......thanks and good luck
