I am projecting my voice to the class and not realizing how loud I am to the camera. This is still a great video for those who want to know how to test a hall effect type cam or crank sensor and they do not have a scope.

Very nice video Danner. I liked how you are breaking videos down to segments for us to learn. I really liked how it's was straight and to the point on how to test hall effect sensors. In addition, I liked how you showed us with a volt meter and compared it to a lab scope. Not all of us diy guys have snap on graphing. I always like it when it is explained on which meter leads are connected to which terminal on the battery and what the dvom is set at when doing electrical testing in video during testing of each wire. Because if it's not explained, I can watch a video and not understand exactly how it was done if there person explaining doesn't explain which terminal on battery he connected to and what his dvom was set at while testing the electrical component. Might I say though, I love all of your videos. Thank you.

For whatever reason my dmm showed both sensor powers and grounds good and then my scanner was showing a good ckp signal and a bad cmp signal. The funny thing is, upon removing the ckp sensor, it was swollen and cracked from oil intrusion from the vc gasket. Installed a new one and it fired right up, yet still shows a bad ckp signal and says out of sync. Silly mopars.

I never actually understood why my meter wasn't "fast enough" to measure a crank sensor, I just know it isn't. Funny thing is, I've scoped them, but never put 2 & 2 together for the time window of high point voltage verse low point voltage as to why my meter isn't fast enough. But when you explain it, it makes perfect sense. Also, in theory with a meter, you should be able to do KOEO and bar the engine over and be able to observe the high and low points no? (As opposed to the bumping demonstration you did with the key)

I found in my Acadia (pull-down system) with P0335, I only saw 0V at signal while manually turning the crank. I then found the connector had signal and ground wires exposed and shorted to each other. I trust the ECU and sensor are still intact. ¯\_(ツ)_/¯ "KEEP CRANKING KEEP CRANKING" 🙂

Hey scannerdanner! Thanks again for all your videos, it’s a ocean full of knowledge! I think I’m ready to buy my scope, i need one to further my diagnosis skills. I registered for my advanced diagnosis class hopefully in the fall, I know you’ve talked about the uscope, I’m on a budget being 20 and paying for college but I received my tax return, I’m stuck between a uscope or a two channel pico. The u scope master kit comes with double the tools for half the price of the two channel pico but having the ability to set markers and zoom in, have a bigger screen, being able to save to my computer I like the pico a lot but I’m getting almost no accessories with the beginner kit. I am a beginner to scopes besides using a verus for fuel pumps and abs sensors. You think spending the extra money on the pico will be better for me in the long run or should I start of smaller with something more user friendly like the UScope?

@@ScannerDanner interesting. I had a case of a bad cam sensor. Code was cam pos sensor open circuit or short to B+. This was in an 05 vw passat 2.8. I checked power and grounds to the sensor. Both present. 5v reference as a power and computer provided ground. However, the signal wire was constantly pegged at 11V. I measured with a fluke dvm. With or without the sensor plugged. The computer was putting out 11V on the signal line, which was ONLY detectable with a dvm. I measured at the sensor side. I measured at the computer. Every time - 11V. I thought the computer was shorted internally. Til I took my led light with integrated volt meter. And it wouldn't measure any voltage. I took a regular old incandesent light and it wouldn't light up at all. But my fluke measured 11V every time. That completely threw me off. So I decided to put a new sensor at that point and the code went away. I don't understand what kind of design this was... could you enlighten me please? Thanks Danner.

When I read the voltage in the two signal wires of the CKP sensor it shows wierd stuff.. Unplugged its 6.2V each. With a new ICM its 4.95V each. Problem is when plugged in to ANY ICM: drops to 1.77V and 0.77V and STAYS there no matter what. I tried 4 different sensors. Acdelco, gm geniuine. One of them would drop to 5.5V and 4.5V. But none will recognize the metal teeth of the harmonic balancer. When tested outside, but plugged in its still the same. Its getting power, i checked every wire for damage, but im not sure about grounding because i checked that with key off for resistance. Between sensor ground to ICM ground (g112) there was 1.5- 3 ohms resistance. Is that too much? Whats going on? Car ran the last time when i changed the CKP sensor. It ran for 2 mins then died and never started. Please help
