Bench Test a 3 Wire Crankshaft Position Sensor

In this video I tackle how to bench test a 3 wire crankshaft position sensor. This would probably work for any hall effect sensor as well. This came out of my 98 Ram 1500, thought the principal should work for many of the 3 wire sensors. Make sure to check your manual and double check the wiring diagrams I have in the video to make sure you're doing it right. I hope this helped, because I could not for the life of me figure out how to test this on a bench and not on a vehicle.

I hope you enjoyed watching this video. If you have any feedback or additional info, I'd love to hear from you. I try to always make quality content that I would like to see myself.

Really hope this helps some people out. Hadn't seen anything like this yet on youtube, so wanted to help fellow car people out.

0 v ok one or not?

Good afternoon I was checking your video and I did a bench test to a crankshaft sensor Hall effect (3 cables) but I supplied 5V with a topdiag 200 tool, other cable to ground and the other to a multimeter to see the voltage flow but the voltage went from 1v to 0 when you approached an iron piece as you do In video, in this case why I have to use a resistance? Can you explain to me thanks

It’s in the perfect spot for the vans. Guess you can’t please everyone

How about a 4 wire crankshaft position sensor. For a 92 Ford ranger 2.3l lima engine 5 speed trans? Can't find a diagnosis video for that.

Appreciate the video and thought this would allow me to test my 3 wire from a 2001 dodge Cummins. I bouught a new camshaft position sensor and hooked it up exactly as you had showed checked and rechecked several time t omake sure the connections were correct. Under these conditions bringing a metal object to the surface of the sensor would not trigger the switch and bring the voltage down - no change. However with the same sensor hooked to the wiring harness of the truck it switches exactly as describes with the metal object. Is this something current related do I need a resistor or more resistors of other sizes beside the 10K? Any insight appreciated.

Try it again but wave the metal in front of the sensor. It works by having metal rush past the sensor and create an electromagnetic field with the sensor. Double check your pinout as it may be slightly different for the Cummins (I know they can be fussy).

@@N0Fumar Thank you for the timely reply. But it worked exactly as you showed when connected to the wiring harness of the truck. Is the truck ECM allowing a different current to pass? Also pinout what do you mean and what should I be attempting to measure?

@@fendercare so the pinout is like the diagram in the book that I show for a few seconds on screen. I'd have to go find it and see if it is different for the Cummins. Try googling "2001 Cummins crankshaft position sensor wiring" and try to match it up how I have it in the picture I show

I have a ram 1500 ecodiesel 3.0. i can not get a digital output from the 3 "new" store bought ckp that i have ordered. do u know if there is some diff. test between 3 wire sensers?

@N0Fumar Жыл бұрын

What year is your diesel? Might have to look up a pinout for that specific year / model

Thanks for the procedure. But the crank in a car turns faster than you probe and so I wonder if the sensor may look fine with a slow test but not work well at a faster pace as required by the ECM. Perhaps a frequency setting on a multimeter may be a better test. Mine fails to show 5V randomly when away from metal.. (as if it gets stuck) but seems to start working again after a few tries.

Well, I mean it's analog electronics that's basically just a hall effect sensor. I guess anything is possible, but my guess is that if it's picking up and sort of reading on the multimeter you are probably fine. If anything, an analog (instead of digital) multimeter would probably be better so you can see swings easier.
