"Service engine soon" light
 

My "service engine soon" light came on today at 3900 miles. This happen to anyone else? I am thinking it is just a "time to get your oil changed" reminder that comes on at a given mileage. Anyone confirm this?

yeah thats all it is the same thing pops up on my pathfinder and civic

you have to reset it


the way i reset it on my pathfinder is i push the trip reset in, hold it
turn the key to the radio position
release it
turn the key off
hold the trip reset again
start the car

its normally gone after that i normally have to fiddle with different combinations to make it happen but i get it to turn off


i dont have a 370 yet i plan on buying a 2010 this spring just gotta sell two of my cars first

i hope this helps

The "Service Engine Soon" light is otherwise known as the Multifunction Indicator Light (MIL). Intuitive, huh? The correct answer is (from the Owner's Manual):

. Malfunction indicator light on steady — An
emission control system malfunction has
been detected. Check the fuel-filler cap. If
the fuel-filler cap is loose or missing, tighten
or install the cap and continue to drive the
vehicle. The light should turn off after a
few driving trips. If the light does not
turn off after a few driving trips, have the
vehicle inspected by a NISSAN dealer. You
do not need to have your vehicle towed to
the dealer.
. Malfunction indicator light blinking — An
engine misfire has been detected which may
damage the emission control system.
To reduce or avoid emission control system
damage:
a) Do not drive at speeds above 45 MPH
(72 km/h).
b) Avoid hard acceleration or deceleration.
c) Avoid steep uphill grades.
d) If possible, reduce the amount of cargo
being hauled or towed.
The malfunction indicator light may stop
blinking and remain on.
Have the vehicle inspected by a NISSAN
dealer. You do not need to have your vehicle
towed to the dealer.

thats funny the MIL is normally a different light than the service "reminder " light

Well, Yesterday I reset the ECU to clear the CEL. Today it came on again. I might go to Checker auto parts tomorrow and see if they can plug the code reader in and see what is causing my CEL.

let me know if its p0456 :D

Service engine soon is a different light than the service reminder light.

Different names for the same thing. Nissan's "service engine soon" (SES), same as "check engine" light (CEL), same as "malfunction indicator lamp" (MIL).

So, SES = CEL = MIL. Any other names for the same thing I've left out.

Depending on what is causing it and if its warrantied or not, it could also be named the "time to take it up the butt without the lube" light or TTTIUTBWTLL. Or we could just trim it down to the "F***-ME LIGHT" or "FML". Just throwing that out there...

Late,

It is indeed the p0456. Evap. emissions leak (small leak).
^^that is what the code reader said. I checked my gas cap. It is on as tight as it can be. What could be causing this?

yup same as mine
i tested my gas cap and no matter how many times i close it tightly and click it several times
it takes no force/effort to remove it
most likely its the problem
there is a TSB for it you might want to mention it to the dealer

do u have any mods. mine was thrown because of the test pipes

mine came on at 100 miles right after the second time i got gas , apparently i didn't tighten the gas cap enuf and air got into the tank , car was running fine , i just had to go back to the dealer to get the light turned off

No power mods, just coilovers and rear camber arms.

The gas cap is on very tight. I am going to take it to the dealership and see what they can find.

did you try a mechanical o2 sim? 90% of the time it keeps the CEL from lighting up with test pipes or race headers

Interesting. I'll remember this when I go to a full exhaust.
