The Check Engine Light is on if the light was not reset after work was done, or it came on again due to encountering another problem. If you just had the engine replaced, then have the system scanned to see what is causing the light to come on. There may simply be something that was left loose or a sensor problem that needs to be repaired. You may have a problem that may hurt the new motor, so it would be best to have the Check Engine Light looked at as soon as you can.
