Cummins crank shaft sensor

0689 was the fault code on this one

[@rhmiks]

Bom dia ! Você poderia me passar esse arquivo com códigos de falhas?

I took the bolt off the sensor. How did you remove it off the hole.

[@misaelguerrero237]

Pull hard with some long vise grip plyers

[@ericmz86]

Would this caused the truck to turn off?

[@themendozafamily5055]

Yes it would . Happened to mind . 16 389 Cummins isx

Good job. Would you mind if I made some suggestions for you?

[@madmotorrepair1748]

busjockey1 wouldn't mind that at all, need all the help I can get lol

Mad Motor Repair When you are checking for Voltage on the sensor the sensor needs to be plugged in and you have to crank the Engine over or have it running so you have current flow through the sensor so if their is a Voltage drop on the power or ground you will see it. When you check for Voltage at a connector unplugged it is static voltage, so basically the meter is only telling you that you don't have an open circuit. And the reason why is because the dvom is high impedance which means high resistance, so the meter will not draw much current, the dvom is basically a differential pressure gauge, so if you have no flow through the differential pressure gauge, just like the dvom, you will not see the pressure drop or Voltage drop. Make sense? I bring this up because years ago when I first started wrenching and didn't know any better I got spanked on a vehicle because I didn't think about this concept. Plus the troubleshooting manual told me how to do it incorrectly. Any way you have some cool videos keep it up. Do you work for a dealer? Or are you independent or by yourself in business?

Mad Motor Repair You could also use a substitute load to test your power and ground to the ref circuit.

busjockey1 wow thank you for the information, greatly appreciated, I will be referring to what you said here on the next time I go to test a sensor! I worked for a truck fleet shooting the hd truck work video's, and the auto work is a hobby of mine for the MMR channel

Ok. What brands of Trucks do you work on and what types of Cummins do you guys run?
