The Service Engine Soon light (a/k/a Check Engine Light) is evidence that something is wrong. That "something" may be any number of things, some major and some minor. It might be nothing more than a loose fuel filler cap. The Engine Control Module (the computer) detected a problem and turned on the Check Engine Light. At the same time it stored one or more Diagnostic Trouble Codes. Get someone to do a DTC readout for you. This is not a big deal, does not require specialized "dealer only" test equipment, and should take less than an hour. When you know the stored DTCs, you will have a fair idea of what repairs are needed. If you like to do your own "wrenching" you can do the DTC readout for yourself.

You will find instructions to do a DTC readout and reset
the Check Engine light at:
