Intermittent SES light - tire pressure?

[woj product]

So, I've got a 97 SL2, 98,000 miles on it.

Every now and then the SES light comes on (no change in performance),
and a couple days later the car magically heals itself and the light
goes out.

I never really noticed a pattern until recently...it seems to heal
itself after filling the tires to their proper levels.

Could something as minor as slightly underinflated front tires cause
the SES light to go on? Anyone ever experience / hear of anything
like this?

No tire pressure sensors in a factory Saturn - you need your PCM scanned
with an OBDII type scanner (if you've got a friend with one or maybe the
guys at your local autoparts store will do it for free)...
