Recently acquired a 2018 Monterey 298ss with twin Volvo Penta V6-240-CE-J(AQ) engines. I’m getting a check engine light on the starboard engine and RPMs seem to be limited to ~2,800 (suggesting to me engine protection mode has come on). Oil pressure is good across both engines. Temps are good across both engines. No other symptoms, just this alert. I don’t have a scanner to hook to it, but the EVC is displaying MID 128, SID 6, FMI 6. I have googled to the ends of the earth and can’t find out what this code means. If anyone here knows, I would be most appreciative. It ran perfectly until now. Unfortunately, not many Volvo mechanics by me so I can’t get someone to look at it for a few weeks.
Update: I ordered a scanner which I should have in a week, but any ideas as to what’s causing this would be appreciated.
