Truck Shut down

do you have the coolant topped off? If its low it will shut down.

 

If one of the arrows on your dash flicker,that could trigger the shut down without warning,I had the same problem with the coolant gauge.

 

What were the exact codes it gave?

Many of the sensors have different codes for different types of faults. Doesn't always mean the sensor itself is bad.

 

Nice feature for engine safety but a PITA when the sensor or harness fails.

 

On newer 4000 series internationals you can just unplug the sensor to turn the light off. The sensor closes the circuit when it senses the coolant is low and kicks the light on. They are prone to failing a lot because of bad design and vibration.

 

My FTLR DD60 14L has an ongoing issue with the low coolant sensor. The plug can be pulled and left hanging - the check engine lite will come on but the engine shutdown warning indicator won't activate. Not the best way to run, but holding the engine override button is pretty annoying. I once shoved a sliver in there and ran 250 miles home that way. Also not the best way to run.

 

I had a 07 Columbia that use to shut down a lot until this day never found the problem. But I unplugged the coolant sensor and replaced the plug with a paper clip. So even if the truck was low on coolant you wouldn't be able to tell because the sensor always read full.

Same with my 08'volvo blew a hole on the block and it kept shutting down and losing throttle(safe mode) swallowing coolant like crazy. Being 100 miles away from home I did the same thing again paper clip into the coolant sensor lol. Got it home no issues.
