As you have done a "Recent" tune up.
Go back and double check that all the plug wires are on good and solid. A consistent but slight misfire can trigger the SES light.
A code reader would probably come up with "Catalyst damaging misfire"
As Theo suggests, get the scan tool on it and it will tell you why it is on.
Hmmm......Loose fuel cap will trigger it as well.........
