remove the battery terminals for about 15 mins, that will reset your computer, if you turn it back on and get the same check engine light there is an underlying problem, only certain codes will trigger that light to come on, you'll need to take it to a mech to be sorted sorry to say, hope all goes well for you, matt

If your lucky, your car is still under warranty. If your warranty is over, you can go to Auto Zone and have the car scanned for the DTC codes. The DTC codes will inform you the issues that need to be addressed so you can have your car running 100% again. Note: Auto Zone scan free of charge and can give you the step by step instruction to address the issues free of charge and if there are any parts that need to be replace, there parts price are reasonable and most of the time are life time replacements. Good luck and keep me posted, be glad to help you get your car running 100% again soon

SOURCE: reduced engine power on
The traction control uses the speed sensor in the transmission and the wheel speed sensors to determine wheel spin. If a wheel spins braking is applied to it so that the power can be transferred to the other wheels. At some point the ECU detected a gross disagreement between the sensors and so as a precaution has entered into a limp home mode. On some systems if the fault is in error it can be cleared by putting the car into drive and moving forward a meter, putting in reverse and going a back a meter and doing this three times. If one or other of the sensors are faulty this process will not allow the error to be cleared. You need to check or have checked the error codes and the speed sensors.
