Hello & Welcome to JA,


When the reduced engine power warning is displayed ,this means the vehicle computer has set a fault code for an engine control sensor or circuit. In this mode the computer is in a "back up" operating system. You will need to have the systems computer scanned for faults.

could this happen if a new radio is installed? also does it serious if it displays that?
Expert:  John replied 6 years ago.
Sometimes when installing any electrical component factory electrical circuits are disturbed & can cause this. A scan will need to be done to see what the problem is exactly,it is possible that something else caused this problem. This is not always a serious problem, nut it will need to be checked & repaired.
