"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,
Trav

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.

have you gotten it check?
brought mine yesterday unfortunately they cant do anything unless the SES light is on
they need a printout of the reading in order for them to work on it and get reimbruse by nissan
my light came on again today(its becoming more frequent)
i wont reset it and bring it this weekend
let me know if u got any updates
i let u know if i get any

I brought it to Nissan today and they told me the same thing. The SES light needs to be on so they can pull the code and do the work under warranty. Looks like I have to wait until the light comes on again.

Update: Brought it to the dealer
Code is still P0456
they said gas cap is good no leaks
culprit was a broken evap control valve
they said since its a new car they needed to call nissan first to report the problem and then do a smoke test to make sure there are no leaks or any other ones

unfortunately nissan is close on weekeds(dealer said)
so i have to bring it back on monday
tech said car is drivabale its just that valve is throwing the SES

will keep you guys updated

btw i know someone here had a similar problem cant remeber who
also the advisor said im the 2nd Z that came there with thise problem
so for everyone just keep it in mind

Thanks for the heads up.

Thanks for the update. BTW, what's you vehicle serial no.? I'm just curious. Here's how you can find your serial no http://www.the370z.com/nissan-370z-g...-decoding.html

tru_Asiatik,

It was me.

If the "Service Engine Soon" light is still on while driving after checking the gas cap is tight, do take your car to the dealer for them to check.
This happened with my car after only 800 miles. They traced the problem back to some leaky seal near the gas tank. They had to order the part and when they replaced it, turned out some cannister next to it was faulty as well. Again they said that part needed to be ordered, that it'll take 3,4 days.
I told them that its a waste of my time to keep coming back. So one of the Service guy suggested swapping the faulty part with one of the unsold 370Z on the lot.
No problem with the light reappearing since.

ok guys Ive been bit by the P0456 bug.. the scanner at Autozone says EVAP CONTROL MALF so Im taking it this saturday to the dealer..

Yeah, add me to the list. My SES light came on yesterday at just about 2000 miles. I'll head to the dealer tomorrow and see what they say.

Can any of the others that have had this problem for some time provide an update as to whether their problems have been resolved without further issues?

Mine has not been back since my last post.

Nissan cleared my light this week, chastised me for not putting the gas cap on tightly enough and sent me on my way. I cranked the gas cap on really tightly after filling up2 days ago. yet, my SES light is back on! Damn

no problems since i got it fix
let the dealer know its an evap leak most likely a bad selenoid
my dealer thought it was the gas cap at first but after 4 trips back n forth to the dealer they decided to do a smoke test and thats what they found

Oh man, I had evap OBD-II code haunt me throughout the entire time I owned my Camaro. Hope it doesn't haunt me with the Z. :/

One of the drawbacks to buying cars off-the-lot.:tup:

I had the same prob. with mine when I drove the first 100 miles. something witht he evap and the fuel cap.

I should have never posted that mine had been gone for so long. Mine came back 2 days ago. I am going to the dealership for something else that broke on the Z anyways so I will see what they can do.

Service Engine Light at 1200 mi
 

I am dropping it off at the dealer this evening. Will post what is discovered.

Looking at my car in the dealer's service bay as we speak. Last time they chastised me for not putting the gas cap on tightly. Even though I knew it was I let them have their say. Today, I am not taking that BS as an excuse. I want an answer. And while I am here, I also have the moving driver seat issue that they need to look at. That issue has been posted in another thread that I won't try to co-opt into this thread, but I'll keep you posted on both issues.

Same here with a Ford Expedition. I know the smoke test very well.

LMAO, I just walked out to the service bay to demonstrate that my gas cap is totally loose. As I am walking back to the waiting area one of the service techs is busy keeping up to date on Facebook. Is this why my service charges are $500 an hour? For him to spend his time on Facebook?

Service Engine = Loose Gas Cap
 

The dealer just called me. The Service Engine Soon light came on because the gas cap was not tight enough. Tech said to tighten it for 10 clicks. He said other new Nissans are having the same issue.

The service adviser, the technician and myself all spent about 5 minutes playing with my gas cap yesterday. Very clearly, when you start to tighten it down, there are some orientations that work and some that don't. We could each start it one way and the cap would tighten nicely. But, if we rotated the cap 180 degrees before starting it the next time, it wouldn't tighten at all. They have a new cap on order for me. I should know by Friday if that fixes the issue.

My light just came on today... but I only have about 1/4 of a tank left, so I find it hard to believe my gas cap is the problem.
Guess I'll be going down to the dealer to see what they say....

Mine has gone away on it's own before I could get to the dealer. 3rd time I have had the SES light. Oh well.

Hello guys,

I need help. I have a p0456 code (small evap leak). This may not be a problem with Americans since your cars are under warranty, I imported my car from the states to asia so my local Nissan dealers don't cover it. besides, they are unfamiliar with the 370z since it has yet to come out locally.

my question is, can anyone tell me which part to replace in order for me to fix this? part number please?

Note: I've cleared the code a few times already and making sure the gas cap is always tight but it still comes back.

THANKS!

you have to turn the cap until it clicks several times not just tight. My first job was as a service attendant at a gas station and we had to do it to all newer cars we usually gave them 2 or three turns around to make sure. those damn caps do break eventually i'm thinking the stant instantfill cap in one of the threads here might be one of my next purchases just because it's cool.
