12.7 intermittent code 43 (low coolant)

If you open your dash panel in front of you there's a computer. There's a metal cover over it. Take that off. There is a switch in there that says not to disable shutdown or something like that. It's VERY obvious.

 

to my knowledge the sensor is not a particular dealer item. all it does is complete contact by way of water/coolant you can take clip off sensor & put a piece of wire or paper clip into the ends to complete circuit. these sensors do go bad. as long at it is straight wired you will be fine. it also could be a loose wire where the pigtail plugs into sensor, that is not uncommon. for future ref I get all my sensors on e bay for 40-80 % less than dealers. they are also detroit parts.

 

huh?

 

If it's a two wire sensor,jump it like heavyhaulerss said. Yes the sensors don't last forever. If you jump it and it goes away,then no wiring issue.

 

Not sure what your confused about. I have the same year and engine as he does. I've already opened mine and switched it off.

 

I say Huh? too. Please explain a little more on exact location. Thanks.

 

How much more exact could I be? I explained above. That's the computer that controls your lights, wipers, cruise control and everything else. Just look behind your dash. IT'S RIGHT THERE!!!

The shutoff switch is also described on the Detroit manual. You can Google it and read about it. Newer trucks have a switch on the dash you hold down for 10 seconds or you can flip the switch on the computer board like I said above.

 

huh? huh ? huh ? Gobble,Gobble. happy turkey day skate-board. just hav'in some fun w/ ya.

 

Have you had your engine washed lately? Once when I got the engine washed that coolant sensor got wet, un plugged it over night, then it was fine.
