Testing crankshaft sensor with an oscilloscope should be easy! However, don't let this catch you out when testing with the PicoScope 2204A or Hantek 1008C! In this video we look at how the low sample rate and memory of these oscilloscope can catch you out during automotive oscilloscope diagnostics!

With an oscilloscope you should check the waveforms only. If they look all right, you should switch to a logic analyzer for this kind of job. Much much more powerful for cheap, as well as as being able to be programmed with multiple triggers, decoding serial/CAN/LIN messages, etc.

@@MechanicMindset yes, it’s like a CANalyzer, although that one is limited to CAN (as the name implies). Probably the best, simplest and fastest to use logic analyzer you can get is Saleae. There are cheaper options though, even open source ones, but that may take longer to setup. Recommend you try one regardless. I bet you’re gonna be mind-blown by what capabilities you’ll get with one :) (there will be little difference between you and the developers at that stage :P)

Works much better with hscope but still best used as a paper weight, I'm not trying to be funny in the least bit. Coupled with a hs502 or 512 , Hscope will do anything that Pico will do on 2 channels. You only get 2 voltage selections even with hscope powering it, 2.4 and 19v and even though hscope will record your pattern for hours and days, it can only record in pages mode with the 1008. Data is there, but not in real time . For reference, you get 1 defined secondary pattern each page. The native 502 and 512 will record hours on a fast signal and days on a slower one in real time. Both cost less than the 1008

Excellent content on oscilloscopes. I really like the HS02 oscilloscope it has 12 bit capabilities and has 8000 samples per second and the software is so user friendly. It also works with Android tablets. This micro-oscilloscope comes in at $100. My favorite low cost.oscilliscope is the Analog Discovery 3 by Diligent. Its.a.small powerhouse at 125 MiSA per channel and 32000 samples per second at 14 bit resolution and the software called waveforms is the best software out there and competes with Pico Automotive. With Academic pricing you get for $200 and the software has automotive features. This is the best 2 channel scope for the price.

I'm looking for oscilloscope automotive use in mind, but as that Pico 2204A has so small memory, was thinking other alternatives. Hantek 6074BC, Pico 2206B or FNRSI DPOX180H. That 2206B is the most expensive of the three, but at least on paper it would be superior except to the FNRSI. However I'd like the pc interface as it's much more easier to handle cursors etc. Would the 6074BC be enough or is the 2206B worth the extra money? 4425 is way out of my budget. Thank you in advance.

This is great to hear! Yes it should work ok. Just try to get something with a good amount of memory too. Sample rate isn’t very useful, if there isn’t enough memory to display those samples on the screen for the time base we select. Bandwidth isn’t so important for us. In fact, sometimes we want a lower bandwidth to reduce interference on the waveform. Hence why Automotive scope has low pass filters - that would be a good feature to have. And math channels 👍

If your not sure about V V T or cam chain tension when your getting 'drift' between cam position sensor and crank position sensor, shouldn't you check idle speed and oil pressure? I'm guessing they both use oil pressure to operate in conjunction with sensors? (opening or closing bypass valves or simple pressure relief?) Checking idle speed isn't too high is something that's been taught since well before electronic ignitions were used, (good old fashioned points and condensors) Mechanical advance mechanisms drop in and out from 'starting' position, your speculating about mechanical not electronic components.

Great point. Not much to adjust on these. There’s no problem with this engine, it’s good as far as we know.

Great informative video. I have a Picoscope 2205a but have not performed that test you carried out. However, the 2205a has over twice the bandwidth, twice the maximum sampling rate (real-time) and twice the equivalent sampling rate Perhaps the 2205 will perform much better than in this test than the 2204a. what are your thoughts on that.

I have the 2405A; it’s only marginally better. It’s the memory that lacks for this test 👍

another possible cause for the cam sensor... its a true VR sensor. voltage output will be proportional to RPM. and theyre hooked up to a schmitt trigger type thing. at low rpm it can take a small difference in velocity to make a large change on the slope of the curve the sensor itself produces, and exactly when it hits the threshold. i know that my VR sensor on a project wont trigger below approximately 400RPM. it simply doesnt make the power at that speed to reach the threshold voltage. the small variation in idle speed may be enough to account for it. wouldnt expect VVT to engage at idle... is that a reading directly at the sensor inputs? no. its after filtering and feeding through the ECU. how? is it direct path? wouldnt seem so... use this effect on small engines, file notches or a ramp in the leading edge of ignition pickup tab, gives a bit more retard at idle, yet acts like normal at high RPM... so you can adjust the sensor position to get a bit more advance at high rpm without affecting the low rpm.

I wouldn’t expect VVT either, I’m wondering if it’s faulty. I’ll check the exhaust cam too and this will help confirm if it is indeed moving or ‘not’ Thanks 👍

Great! Voltage (height) and time are the main 2 settings. Starting with 20ms/div and 20V are good base settings to get most waveforms. Adjust from there. We’ve got a few videos helping g with this 👍

I bet the pulstime from the cranksensor is 45usec independent with rpm ? Try turning the crankshaft backwards and measure it again:)

You thinking it’s an active sensor? I saw these a while back at Audi, and they give a signal with the ignition on/engine off (this one doesn’t). However, im gonna try this for sure! 👍

I'm curious, you've already addressed the 1008c for resolution kzbin.info/www/bejne/Z2Svi2iGlN91d68si=pKS7RxFxS67aJVrw so am I correct that this is not an issue for the 6022be? This is what I already have. I'm a shade tree guy, so I want to get as much use out of cheap stuff as possible. I'm not likely to be touching bmw at this stage, but if I want to do a timing chain they'd be high on my list.

It will probably have similar results to the 2204A. I think the main point is, if you get a waveform like this, don’t assume the car is at fault. It could be scope specs. You may never see a sensor signal like this, but they are getting more common on later vehicles. Just one to be aware of 👍

@@MechanicMindset no doubt as technology processes things are less likely to fail in one area but newer ideas transfer to another ie timing chains prone to stretching. Seems to be a modern feature of long service intervals, single row timing chains.

Good video ive got a mondeo 2.0 deisel that keeps cutting out and showing no fault code , im going to have a go with my recently purchased 4225a and the guided diagnostics on early access , will he my first attempt at using the scope properly , i could do with getting hold of some onown good waveforms to compare to , and i no i cheaped out and didnt buy the 4425a but will get that in time when im more indepth with it all , any info on down loading known good wave forms would he very much appreciated , im sure there is a way on my MM app but i just need more time to study it all
@MechanicMindset
@MechanicMindset 4 ай бұрын
When searching the waveform library, less info in the filter will give more results (ie multiple vehicles will likely share your engine) You can always jump in the MM community for support, and there are some great waveform sharing groups out there. 👍

HSCOPE has a way running in a pages record mode with the 1008c. There is a gap between the pages but it definitely makes the 1008c a little better. As a scope enthusiast I own way too many scopes ( high end and low end ) I still am amazed at my hs502 and my hs402 wifi with an internal battery. I would pay 10 times the price , I just think HSCOPE really has more features then some of the high end scopes. Here is a link to the gadgets playlist demonstrating the new capture mode. Hopefully it okay to leave. Please delete if not. kzbin.info/www/bejne/iKCamoJpZ8etiLc
