Best Answer

To answer specifically what is wrong with your vehicle will be impossible without more information. The check engine light comes on when the PCM(computer) sees a problem somewhere in the engine or transmission control system. A sensor may have failed, a solenoid or actuator may have failed, a wiring problem may have developed, or there could even be a problem with the PCM itself. You will have to have a diagnostic run on the vehicle.
