Service Engine Soon light

[2003_ZX2]

Hi,

My 2003 ZX2 has about 38k miles and has been running great with no issues whatsoever until tonight when the "Service Engine Soon" light came on. I stopped to check things out, but couldn't discover any problems...no unusual sounds or vibrations or odors. Oil level fine. The manual said it likely means a component of the emission control system has failed.

I drove on home and couldn't notice anything unusual except for the SES light remaining on the entire time. Any ideas on simple things I can check before I turn it over to a mechanic?

Have you had it checked yet? Mine had the same problem and it turned out to be the transmission shift solenoid. A lot of times the light indicated problems with the transimission.
