Hello , my name is Joe

I apologize for any confusion , I see your question is in the "Q & A " format.

Cummins Fault Code: 235
PID: P 111
SPN: 111
FMI: 1

Coolant level signal at pin 27 and pin 37 of the engine harness indicates coolant level is low.
graphic

Power and/or speed derates and possible engine shutdown if engine protection shutdown feature is enabled.


The coolant level sensor monitors the coolant level within the coolant system and passes information to the electronic control module (ECM) through the engine harness. Because this sensor is complex, do not use a multimeter to check it. If the radiator coolant level drops below a certain level, a progressive power and/or speed derate will occur. Engine can, perhaps, shut down if the engine protection shutdown feature is enabled.
The coolant level sensor is located in the radiator top tank or surge tank.

please verify that the error is coolant sensor related


the engine is running between 200-212 degrees f


sounds high to me

Expert:  Joe replied 1 year ago.
The fault code indicates low coolant level , meaning that the engine may be low on coolant.

The coolant sensor will be in the top radiator tank , or in the side of the "coolant overflow" tank.

The coolant temp. is a little high , Make sure the radiator fins are clean and inspect the lower radiator to make sure the fins are not coming apart.
