The EPC indicator symbol on the dash of a car stands for "electronic power control." The light comes on when there is a problem with the engine.
If the car also has an electronic stability program, this light also comes on to indicate that the program has been turned off. Once the problem with the engine is fixed, both lights turn off. In some vehicles, the EPC limits the amount of throttle that can be used so that the engine is not damaged. If this happens, the car can be driven to get it fixed but it does not accelerate past a certain point.
