2010 twin mercruisers 496's sterndrives with DTS/ Axius. I'm getting an alarm on vesselview "Sensor Power Supply voltage low". I've checked the 5 volts on the manifold, temperature and water pressure sensors and they are all at a solid 5 volts. Also, this alarm is both in the active alarms and the history and I can delete any other alarms except for this alarm in history. It won't clear in history.
 
I just got the same thing. Did you ever find a solution? I have a 350 MAG MPI EC. Just threw the Sensor Supply Voltage B "Sensor power supply voltage is low." Of note, the pitot speedometer dropped to zero. Could this sensor have shorted? I will look for it when I trouble shoot this week and see if it throws the code with it unplugged.
 
OK...my issue was the trim sensor on the starboard side. The wires deteriorated to the point where they broke and created a short. Cleared the short, the voltage error went away. May not have been your issue but I'm logging my fix incase someone else get has a similar issue.
