Hello! Welcome to justanswer!

It means the computer found a fault in the engine or trans control systems. So now its limiting your engine power to mitigate the problem it sees now. It needs to be hooked up to a computer to see whats really wrong. If the light flashes, that means the engine is not running on all cylinders. If its solid that mens something the computer controls is not working.
