I'm at home for the day so I can't get the fan but I know the fan parameter is set to on/off. I have a diesel laptop and that's the only fan parameter I have

Cv713 

And the temp Guage appears to be operating as it should 

The fan cycles with the a/c on

I apologize for my typing skills. Bruckners said there was a coolant temp sensor by the oil filters but there isn't one that I could see

There is only one temp sensor I see in the water manifold and it points straight to the rear and the wiring looks good

No recent changes to the ecm that I'm aware of

Bruckners said there was behind the oil filters but there isn't 

2006 granite, engine fan works with a/c and stays engaged when air pressure is low but won't turn on with high engine temp. What is going on?

Hello everyone, I have a mid 128 sid 254 fmi 4 code. The engine intermittently dies like you turn the key off, it may run for 5 seconds or 5 minutes with no consistency at all. I checked the battery terminals and all the grounds i could find, I have checked the wiring by the by the vcu where it rubs on the panel, i have checked the wiring bulk heads and even connectors and used dielectric grease on them when reconnected. Does anyone have a clue what is going on?
