CAUSES
Faulty Engine Mount 'A'
Engine Mount 'A' harness is open or shorted
Engine Mount 'A' circuit poor electrical connection
It means that the wire(s) connected from and to the component (sensor, solenoids, actuator, etc.) is either open (cut, broken, disconnected) or shorted (touching other wires, components, body). "Open" and "short" are common electrical terms. An open is a break in a wire or at a connection. A short is an accidental connection of the wire to ground or another wire.
In simple electronics, this usually means something won't work at all. With complex electronics (such as ECMs or PCMs) this can sometimes mean something works, but not the way it's supposed to.
