Hi There, The check engine light can come on for a variety of different reasons. If a specific part has been replaced, the check engine light be remain on if that part was a part that required a system relearn which is common for some parts such as a fuel injection throttle body. We would need a bit more information as to what specifically was replaced in order to properly diagnose your car. I would suggest having a professional from YourMechanic come to your location to diagnose your car using a scanner tool which will help to narrow down the issue more specifically.
