the engine light is a generic fault indicator in your car to point out something is not quite right with the engine, having a loss of power as well is also known in some areas as Limp Mode or Safety Mode. it means the car is restricting the power it gives to ensure no damage it done to the engine.
the only certain way to find out what is wrong is to take it to a garage that has diagnostics equipment that can read the fault codes from the vechicles ECU (the fault codes will be the reason the light on the dash has come on as its reporting a fault somewhere)..
your mechanic should be able to tell you what is wrong with the engine from that and give you a more accurate cost at fixing it.

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.
