Get a code reader and find out what code its throwing.

Tighten your gas cap.

more than likely you have a "Small Evap Leak"

nothing serious just make sure you closed the gas cap right. (click it a few times to be sure)

thankx for info ill see if turns on again tommorow when head back to los angeles if it doesnt turn back on u think i should worry still or forget abt it

If it blinks = serious trouble.

Regardless I would check vitals in the morning before turning the car on.


Check oil, water.

when it came on lst time just popped on no blinking then turned off and wen turned on just popped out no blinking at all..ya im gng to check liquids in the morning ill let it sit over night so can get oil level right because hate that dip stick...

happened to my sentra.. turned out to be the gas cap.. hope this is the same for you.

blinking = mis-fires then it goes into limp mode.



But no solid could be a sensor.

If the car isnt acting up chances are it's just the gas cap.

^ what does limp mode mean?
if light blinks is it serious?

Limp = Car will only let you rev to like 3k or less

Blinking means its a "EMERGENCY" and to pull the hell over and turn off the engine asap

LOL! ok good to know that. loved how u explained it :bowrofl::bowrofl::bowrofl:

The Screen Was Savers :)

Next time it comes on, go to auto zone and have the code read. More than likely it will be stored as a "pending dtc" if the light isn't on at the time.

Get the code number and then you can accurately diagnose the issue.

i would do thanx for the advise... im going to take off in a bit just checked water its good oil missing about half a quart stop by auto zone and buy a quart and put half...hopefully stays off..if it doesnt turn back on u think i should still worry?

I've never heard of any SES lights being triggered by having low fluids. If it happens again, go to autozone and have the codes read by an ODBII reader like someone said earlier.
