Check engine code 111

[emil2]

This is my first time on line. I have a 2005 Monaco Cayman with a Cummins 300 ISB the check engine is on. Code 111 Coolant level low voltage. How can I check this sensor? Where can I get a replacement?

The first thing you should check is your coolant level. If that is OK, any Cummins dealer should have the correct replacement sensor if that is the problem.

The commums dealers in this area said they could not supply the sensor I would have to go back to the motor home manufacture for it. Call Monaco they are sending out a new sensor. I hope this solves my problem

The radiator and coolant overflow/fill tanks are supplied by the chassis manufacturer (Roadmaster division of Monaco, in this case) rather than by Cummins.

I had the same issue on my FRED. I obtained the new sensor from Freightliner.
