As I mentioned before, I’ve been tackling this intermittent issues for a long time and you, my friend are an inspiration To me as usual, thank you for sharing your knowledge,stay well warrior🥋
I would have called crank sensor after seeing that capture, the signal stays high when it fails, so the sensor is not switching the supply voltage to ground. Never would have considered a shifted bellhousing...thank you for putting this out.
Just found your very interesting channel. Those spikes are not high current but high voltage that scatters through the different signal paths. Ideally you shield the two wires from the crank sensor signal. The voltage spike could be caused by ie a failing injector causing a ignition misfire that causes a very high voltage spike caused by the lack of fuel. I encounter a cranksensor that was scratch by the fly wheel because the forgot to put in filler ring so that there is sufficient gap space between the sensor and the flywheel
Very interesting to a scope new comer to see that it can pick up noise from other electro mechanical devices. It’s something that makes sense as soon as you think about it, kind of like the lights fading when the vacuum gets turned on but at a smaller scale. Thanks for sharing.
I’ve seen the same thing on an NV a tech at my dealership decided the dowel pins weren’t important and couldn’t fix the crank sensor code after installation…you in the NY area haha wouldn’t be surprised if it was from our guy…😂
I think so. Can't say for 100%. My scope is a common ground so I always go to battery ground, especially when I use more than 1 channel. I would have try it to prove it out. Good question.

Absolutely 💯,
Excellent diagnosis & even better presentation. Thank you.
Thank you👍

Good luck on your scope journey. Lots of cool things can be seen, with a good scope and proper set up.! Thanks for commenting.

Who needs them dowel pins anyway. 😄 🤣 Thanks for commenting 🤘.
Thank you Carter, for bringing the light to us with your vast experience. Blessings

WOW!
What a Great case study/diag Mike. Thank you for posting!!
No problem 😄💯
GREAT VIDEO , COULD YOU OF USED THE CRANKSHAFT SENSOR GROUND TO TAKE AWAY THE NOISE?
I think so. Can't say for 100%.

Good video Mr Carter
Have you considered posting this on something like diagnostic network perhaps, i think this would definitely help people.
I'll have to check into it. Feel free to share it there if you want!
Diagnostic Network is similar to iATN.
@@CartersDiagnostics okay, I will.
Great catch!!! Wrong hole never end well
Hahaha 🤣🤣
Can we record like 5 hours
Using pico scope? GREAT vidos 👍 👌
That would be fun!
Nice catch. Love these videos
Thanks💯
Tutorial brilliant ,Carter's Diagnostics

Cool diag thanks for sharing.
👍
Excellent MIKE thank you
💯
Why is there such a high signal on the ground at 2:32?
Most likely noise.
Great video thank’s
👍
