Ok let's clarify - are you getting "EML" ? It is a yellow light...it says EML. That is engine safety mode, or whatever you want to call it. If so, there are a variety of things that can cause that. EML clears itself when you shut off the car, unlike many other SES codes.

EML is not the same as trans failsafe...I have a manual trans, and therefore no trans failsafe mode...but I get EML occasionally.

Getting EML is usually accompanied by another code - check the codes just in case you have something on top of the gas/emissions system fault you are aware of.
