Great captured Pico Ben. Question, can you do some more videos using the math channel to locate issues like misfires, drop out, what does A+B means,etc. If possible thanks
A lot of the Chinese manufacturers are producing junk I went on a diagonal the other day and the guy had put a brand new crank sensor in this 2500 Chevy Silverado pick up here in the United States. Him and another guy had been working on cars all their life they were standing around scratching their heads. My buddy said give me a call and I tried to coach him over the phone being a nice guy. Or maybe just shooting myself in the foot LOL. I can’t make money giving free advice lol. Anyhow it turned out that they put a new crank sensor in it but they bought it from an auto parts store that had purchased it from China and it was a bad part. Caught it with the scan tool and backed it up with the oscilloscope! Great video thanks! Some of these new parts are bad right out of the box! I don’t know if you’re experiencing that over there?
Great work Ben as always 👌. I am enjoying my 4425A and trying to get the most out of it, it is a very interesting peace of kit and Pico 7 software is 👌👌👌. i can't get enough of Pico keep up the good work
Great capture Ben. I've had a few of these and the sensor goes high resistance usually. I suspect the sensor actually went open circuit and you were seeing a loop of signal through the scope, rather than a short circuit condition. Especially as it an AC signal. Just a thought!
Thanks Mark, and after I filmed it and thought about it the chances of it shorting are quite rare! Always the way when you're looking at things in the heat of the moment!
@@markstammersdiagnostics9784 Its tough at the best of times and with the owner of the vehicle sat in my living room there was added pressure to get it done! Hats off to all those that film on the go. It's a skill for certain. Just hope there's something in there that people can take away.
@@benmartins6283 I know what you mean, it's not for me. But yes, there is always something to be learned from a good honest description of utilising the scope. Good job.
@@markstammersdiagnostics9784 Could you explain to me: "I suspect that the sensor actually opened a circuit and you saw a signal loop in the scope, not a short circuit. Especially since it's an AC signal." Wouldn't a short circuit cause the same signal as in the video? What's going on with this signal loop? Thank you
Hi, resistance was measured using the BNC+ Resistance lead - TA432 www.picoauto.com/products/test-leads/picobnc-resistance-test-lead. It can only be used with the new 4225A or 4425A scopes.

Amazing class, always the best and simple solution, thanks for share that video and a little bit of your experience
Thanks for this video Pico Ben... hello from Chicago Illinois in the United States
I didn't realize that the math channels were now working on the Pico 7. Good news to me.
Thanks Ben, another great video

@@benmartins6283 I agree with you there. I have to try hard to walk away and analyse my captures, before making a diagnosis, for that very reason.

Great stuff with the maths channel
Gold! Thanks for sharing 👍
thank for video
Какой щуп ты использовал для измерения сопротивления?

@@benmartins6283 Привет, есть в продаже осциллограф 4225А? На сайте написано, что временно отсутствует! Возможно эта старая информация
@@timotiqwerty1927 Sadly that is still correct. I mentioned the 4225A in case those that have one already could make use of the resistance lead.
@@benmartins6283 Спасибо!
