service engine soon 1997 pontiac transport

I have a pontiac transport with 106,000 miles(6 clyinder). recently we made a 3 hour trip (1.5 hr. each way) and on the way home the service engine soon light came on. When we got home I open the hood and everything seems fine. the engine is not making and strange noises and no driving problems, it is running perfectly fine. I was just curious as to what the problem might be. thanks

When the light came on, it stored a diagnostic trouble code, you need to find out what that code is.

Trouble codes

A lot of auto parts stores will hook up a scanner to the car (OBD-II) and let you know the code behind the light (at no or a small charge).

I THINK this model will turn on the light if the gas cap is loose!!!

You are correct


But, as stated, you will never know why the light came on until you have the scanner pull the DTC.

You are correct! But I say who cares about the code if the cap is confirmed to be loose. Code will go away after several key cycles.
