I am getting a code 197 for low coolant level when the bottle is full. Tried a new switch and a bottle. It is turning on the Stop Engine light and the check engine light.

Ok, need to get the engine size and is the code P0197?

Customer: replied 1 year ago.
6.7 ISB. it just says 197.

Not using OBD codes. Scanning through Cummins connector.
Expert:  Eric replied 1 year ago.


Ok, according the FCM, I am showing it as for the EOT(engine oil temperature) sensor, not the low coolant level sensor(see attachments)

You need to check harness connector to the EOT sensor for cuts, breaks or loose wiring and repair as needed. If ok, replace the EOT sensor

This truck has a Cummins 6.7, not a Ford 6.7.

Ignore the diagram of the EOT sensor I just sent you. Here is for your cummins

Customer: replied 1 year ago.
That diagram is not showing the switch. My switch is in the coolant reservoir bottle. There are two wires going to it. A light green and white and a black and white, assuming that is ground.

I will opt out. I show the code as being for the eot sensor, not the coolant level sensor
