2013 300xs

Getting an alarm, sometimes at start up, then just randomly.

Smartcraft says "sensor power supply voltage is low"

Battery is an Interstate 31MAGM 800CCA 1160MCA and is about 3 months old. No issues until yesterday.

Smartcraft shows 13.8 to 14 volts when running.


Any particular connections I should check on the engine? I checked the battery connections and they were tight. I am using the clamp on style connector. Possibly a bad sensor?

Need the faults read, to diagnose the conditions at which time the fault occurred.

Going thru this now, check wiring on 5v circuit. Probably have short or bad connection somewhere
