The engine check light is warning you that something is wrong with the engine.
The light will go out once you have fixed the problem.
Get the vehicle's OBDII port scanned with a scantool to find out if any DTC codes (diagnostic troubleshooting codes) have been logged. The code will tell you what the problem is.
If you're in the USA major auto spare parts retailers e.g. AutoZone, PepBoys, O'Reilley's etc will scan the port for free.
