Testing CKP and CMP sensors (Hall-effect)

Testing both aCKP and CMP sensors with multimeter and sn oscilloscope. A waveform can reflect problems that can easily be missed using a voltmeter.

With snap on scopes you need to zoom way in in order to increase the sample rate then you can pause it and zoom out to see the details of your CMP/CKP . There’s a term with oscilloscopes called “aliasing” and it happens when you zoom out to a slower time base and there isn’t enough sample points to capture the details of the signal. Snap on scopes have a comparatively lower sample rate so in order to get the most detail you have to zoom to lets say a 20mS sweep to get a good view of the CPK sensor . Then you would stop the recording and zoom out to get your CMP sensors and and CPK in a view that you’re ok with to verify their synchronization.

Good comment sir. Question in your personal opinion wich osiloscope is better pico or snap on I just trying to see so I can decide I don’t know anything about osiloscope but i heard osiloscope are good tool . Thanks

@@jordysandino6577 pico hands down I have a Pico and it has so much more to offer then the snap on scope .

[@MRDIAGNOSTECH]

Picoscope is a great scope to have.

Watching it again you really are great teacher. Details details. Love this channel 👊🏻👍🏻

Excellent tutorial. I'm a DIY guy. This complete explanation from the wiring diagram to the testing procedure is very helpful. I was able to follow the process and understand it completely.

[@MRDIAGNOSTECH]

Glad it helped

[@abdelhakdhm4837]

Thank you for your explanations:) Also There is possiblity to use the cycle duty mode of the multimeter to see the signal.

Bonito video primo . Me sirve para aprender. Me gustaría ver que nos explique en pico osiloscopio primo . Gracias

I SEE NOW CLEARLY ,,,,,,,,,,,,,,,, SNAP-ON SCOPES ARE NOWHERE AS GOOD AS PICO . CAN'T WAIT FOR THE NEW HAND HELD TWO CHANNEL PICO TO HIT THE MARKET !!!!!!!!

Good video sir . Question Can the vehicle start and run without ckp? Is that normal?

[@MRDIAGNOSTECH]

Yes it can. The PCM will reference the CMP to synchronize fuel delivery and spark, but it will take a long crank before it starts.

[@jordysandino6577]

Can start without ckp? Thank you sir

[@MRDIAGNOSTECH]

In most vehicles today, the car will start without a CKP. The PCM will reference the CMP to synchronize fuel delivery, but it will take a long crank before it starts.
