EASY Fuel Injector Testing | Automotive Oscilloscope Diagnostics | Mechanic Mindset

Join Mechanic Mindset and get a FREE multimeter!

How to test a fuel injector using an oscilloscope; this video looks at the voltage waveform. We look at fuel injector waveform analysis where we can identify resistive circuit faults and see pintle movement. I am using the PicoScope 2204A, a super affordable oscilloscope set up.

I understand your way of explaining these things more than the actual courses i have completed at manufacturer training centres.

[bensiemers]

Exceptional instruction. Consistent and detailed in every video. Top notch.

Thank you Darren, for this excellent and very informative video!

[jdmackable]

Thanks so much for taking the time to make these videos Darren.
You do a great job explaining yourself in a non intimidating manner. Was really happy to see your notification of new content as I'm in Covid isolation and going stir crazy.
Keep up the good work and take care!

[billyyoder]

Thank you Darren. Good job again. God bless you and your family.

[Zkttimandjes]

Wow! Great info here! Thanks so much for sharing that information about how to get that pintle hump to show up on the fuel injector by adjusting the scale, the resolution, and the time. That was very helpful!

[markoguberinic]

I love your video, I started using oscilloscope and you help me a lot thank you. Кeep up the good work and take care!

[TrevAutoTech]

Another great video... easy to follow . Easy to understand as always.

New subscriber and an excellent informative video. Thank you for sharing. Everyone starts with the big expensive scopes glad to see your using what I have. Yes it’s two channels but it’s very good. I’m a retired aircraft mechanic Diyer so I will be following your channel. Very easy to follow and understand. Thanks for sharing Artie 👍😊

Hello Darren, happy new year to you, looking forward to watching this tonight.

[scarabe-ing]

Thank you so much from France !
I love your videos and your particular style.
You help me a lot.

I do love my Picoscope once I've got it set up. If I wasn't a mobile tech I'd have it permanently set up on a mobile cart. I find it much easier to get out my Fluke 190-204. But even that becomes a hassle because of its size. It seems a bit silly of me complaining about its size, when I started in the late seventies the scope I used was too tall to see over and was nearly as wide as the car I was working on. I just ordered the Owon HDS4202M-N 2 channel 200mhz 1gsa scope. It's a bit pricey compared to a lot of handheld offerings, but it still pales in comparison to the Fluke (ouch, that hurt). We'll see, the channels aren't isolated so hopefully I don't send any smoke signals with it.

It’s Funny I got my A 2204A on Sunday I was outside on Wednesday doing my own injector waveforms and got the same image, the extra settings are handy as I didn’t think I was getting the pintal move movements showing up I will try again when I’m next off. I got a cam crank correlation but I setup the scope wrong and got a ton of data on the screen you really have to zoom in a lot to get the detail. I will try again with this just not been the weather lately as you know. Keep up with the great videos I have learned a lot from you already. All the best. Steve.

Thanks Darren, your videos is what I always looked for for using Oscilloscopes on Automotive.

[bencosturbz]

love these vids im going to join up for the corses,

[rsbharley]

excellent video, thanks for sharing. Cheers

[crasher]

Great video now we need an injector wave form analysis on gdi injectors

[alrifainidal]

great video and nice explanation Mate . thanks friend hopefully we can see the current waveform next time

[GerardBurkeBurkesGarage]

Nice video mate,
Learnt some new info in this one.
Thanks for sharing & happy new year to ya 👍
