So did you replace the fluid and sensor after the original light came on? or did this low coolant light come on after you did flush.

I have seen people get this message when they dont put in enough fluid from a flush and attempt to burp the block and then play catch up with adding fluid.

Did you have trouble bleeding the system? are you getting different reading levels on your coolant if you check in the morning? usually i seen upper rad hose or by the y connector are known leak areas and those spots have caused the same low coolant warning.
