Could be as simple as the gas cap being loose and not sealing properly, or a multitude of other conditions that the engine diagnostics picked up. You can buy an inexpensive code reader or a more sophisticated scanner to read the OBD-II codes to determine the problem. Autoparts places like Autozone offer free services to scan your car also to let you know what trouble code is logged.
From there, you can check on the Internet to find possible fixes, or bring it to a shop with at least some knowledge of what the issue might be.

Would your engine light come on if your ABS and brake light come on?


If the ABS warning light comes on the engine light should not come on as well. ABS light shows there is something wrong with the brakes. The engine light shows that there is something wrong with the engine.

Check engine light on with the TPS code. replaced TPS and pig tail and it checked out OK with volt meter. The light still comes back on with the TPS code


Check engine light comes on and off, these are indication that there is some error code stored in your vehicles ECM. The engine module computer needs to be scanned. These will give the code and as per the error code the further problem can be detected and confirmed. The engine light indicator blinks or remains steady on dash when engine computer noticed any problem with any engine electrically operated components.

Check engine light comes on and then it starts


Many things can cause the light to go on.  Instead of giving you many guesses, you should go to the auto parts store and have them hook up their computer to look for trouble codes.  Let the vehicle tell you whats wrong instead of guessing and spending a lot of money on the wrong parts.
