is this a common thing for 350z's? after a driving my car hard for about 30mins the light comes on , then when i wake up in the morning to take it to dealer the light is gone then, a few days later it comes back on out of no where?!?... just wondering if this is a steady problem in the 350 community, mods are a intake

 

No, there's nothing common about a SES/CEL. Take it to Autozone and get the code read - obviously there some problem.

 

ill take it to the dealer saturday and see what it is, Im hoping its a faulty gas cap because it came on once after the dealer filled it then when it got low on gas again i noticed it came on...

 

found out it was a code for the throttle body needed it clean

 

Do you guys get the dealer to read your code without the BS "diagnosis charge" of over $100? They charge you to even look at the car, I hate dealerships.

 

Dude go to autozone they do it for free lol.

 

That's just a generic code most of the time, it doesn't tell you exactly what needs to be done to fix it. That they charge $100 for even if it just turns out to be the gas cap is lose. On cars I've had where it was the gas cap, all the autozone think said was "emissions evap system" or something along those lines. Which could be anything in the fuel system.

Shouldn't they look at the car for free under warranty?

 

I just went in this past Tuesday to get a state inspection. Apparently everything passed fine. I then drove the car on Wednesday and Friday. I noticed my "Service Engine Soon" light was on. I went in Friday as soon as I noticed it but it was late in the day (and the service adviser told me to come in Saturday).

While I was there, I got my oil changed but and the light looked at. The adviser said it originally could be the gas cap was loose. I opened up the cover and it was on nice and snug. Apparently the test was run, the guy told me it was related to the evap system. Again they said maybe due to loose gas cap. How can this be when I know I tighten the cap as I usually do?

I read some other articles and they also mentioned that it could be the gas cap isn't making a tight seal anymore. We'll I'm out $90 just for the check.

If we found out the code from Autozone (and it was an evap issue), is there anyway to reset this code outside of going to the dealership?

 

My light is always on.

Thanks, Utec.

 

Mine just came on, but im turbo charged and i just passed smog so i hoping its nothing to crazy. Taking it to my mechanic tomorrow. Luckily he doesnt charge me

 

i got about 5 codes right now for all kindsa sht. Air fuel metering, 02 sensors, and other stuff.

 

so SES light are the same as CEL? or does the 350z have a CEL?

 

the last and only time i went to the dealer they charged me 200 dollars to run a diagnostic test on it - and they still were wrong about what the problem was...
