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.

SOURCE: my engine light came on
Hi, the check engine light is the summary of the problem you are facing with the truck.
The "Check Engine" light means THERE IS A PROBLEM with either engine performance and/or emission controls and should be repaired ASAP. This light DOES set codes in the computer and can be scanned with an OBD2 scan tool. Most auto parts stores and auto zone will do this as a free service. When you get the code, it will be interpreted to know the exact problem with the car so it can be repaired...

I would advise to take it to a shop you trust and let them scan your vehicle for trouble codes. From there they can give you an idea as to why these messages appeared. : )
