Excellent information thanks .!
great training platforms! Understandable format! I have a passion for this training!
Thank you

Awesome video, My Electronic Throttle is making exactly the sound at 4:56 in your video on ignition on. Is this bad throttle or bad ECU? Can you please point me in the direction to figure out?
Hey bro, I have the same sound, did you find out what the problem was?
I put the Volant Cold Air W/scoop on my 11’ 2500HD. After driving it for a few days and stuffing my foot in the bore, sometimes I get this noise, at high RPM.
Great, thanks. What is the Bosch, Siemens ECU driver frequency for throttle body and VVt solenoids?
About 25 KHz. Our unit follows exactly those parameters. www.autodiagnosticsandpublishing.com/etc_electrothrottle_electronic_throttle_tester.html
Nice presentation.
I was wondering if this issue could be picked up on a lab scope and what sort of pattern I would look for to determine if the resonance frequency was coming from the PCM driver or if it was the ETB itself
That is a nice argument, I do have a database of faulty unit waveforms and a few defective ETB to choose from. Maybe I'll do a video on it, as to how the vibrating winning transfers to the waveform. When developing the Electrothrottle Actuator 2 years ago, I remember seeing that the ground shifted slightly from 0.00v as it was happening. I have to do more research and document this. Thanks for viewing and sharing, Mandy.
ADPTraining good idea!

very interesting info. Note the PWM directly drives a DC Motor so high frequencies carrier above 20kHz are not effective with the motor magnetic core

It is possible that faulty throttle in diesel engine can demage dual mass fly wheel? I mean situation when the throttle doesn't close completly while turning off engine causing shivering of the engine.
Meaning engine shaking? Probably not, as Diesels are tough cookies. But, flywheel can become loose due to shaking...
@@ADPTraining Yes. Engine shaking. What kind of loose? Inside of the dual mass fly wheel?

I have a 2008 Nissan 350Z that was making this resonant humming noise when you would put the key to ON position ( like what you show in this video on the test bench) . I thought throttle body was bad so I replaced the one with this symptom (car has dual throttle bodies) and after I replaced it the buzzing was there, but then it went away for a while and now its back again. If it's the ECM as you say doing it, then why would the problem be intermittent and coming and going. Also can the vehicles entire electrical system be responsible for this? Example is the load on the electrical system from say a larger CCA battery than the ECM was designed around? I ask because my car has a larger CCA battery that was used for a subwoofer system, it's a Optima large battery , red top and its seems to have more amps than a regular sized battery for this engine. Let me know your thoughts on this and what I should do next thank you!
First a larger battery in principle shouldn't be a problem.
Second, newer cars are more susceptible to battery changes, yours is not.
Third, look into EMI from the alternator, ignition, etc. Also make sure all grounds are correct.
That's a lot of testing, but it's my five cents.
@@ADPTraining Thank you for the reply, the humming noise went away again, its intermittent it seems like, or maybe the car learned the programming of the sensor so now it isn't trying to shut an already shut throttle body. the noise it was making before sounded like the motor was trying to force the butterfly closed but it was already at closed position. im not sure but the sound has gone away again, i think maybe it did a relearn or something from turning the ignition from off to on repeatedly.
Where can find this device, also can put switch on click door or etc that means fine or issue with etc?

What are trying to say here? I have high pulling power in my car after throttle body cleaning, its like even if I press brake pedal, car throttle on it's own to some extent., please help. Is my throttle body damaged? If then why so?
Resonant frequency has nothing to do with your problem. There's an APP to Throttle correlation problem. Use my ELECTROTHROTTLE tool to test the throttle, then go from there. Here it is... www.autodiagnosticsandpublishing.com/DealsToday.html

I loss power press on gas and I takes a wile for it to go but if I turn the car of and back on I comes back to normal ???? Is it this the throttle
Look up and test both, electronic throttle and APP sensor. Use my ELECTROTHROTTLE Tester and Blue Voltage to do the testing. See here.

I put the Volant Cold Air W/scoop (3535365) on my 11’ 2500HD. After driving it for a few days and stuffing my foot in the bore, sometimes I get this noise, at high RPM.
Makes no sense to me.
On my 2006 dodge ram. App.2. Waveform shows voltage drop But is this normal ?
When i press the gas pedal the fuel pressure drops 30 psi. And its a new fuel pump. Is this voltage drop has to do something with this fuel pressure drops ?
Ok, App 2 drops voltage where? The reference voltage or the signal. Also, fuel pump pressure should no be related to App sensor, unless there's a short.

All these Electronic Throttle testers i have seen dont seem to be able to test at part throttle. They just seem to change the sweep rate. It would be nice to be able to hold the throttle plate at a certain position accurately and then check to see if the butterfly is vibrating there and monitor the tps sensors on a scope.
+Tech Tune Automotive Repairs Tech Tune, I designed the unit to hold any throttle position. Slowly adjust knob, once there, keep it and that's it. But just curious, why would you want to keep it at part throttle.
+Tech Tune Automotive Repairs I designed the ELECTROTHOTTLE to keep whatever position you give it.
Is a throttle body supposed to open all the way with the car on not started with pedal fully pressed?
Depends on brand.
@@ADPTraining it’s just the one Hyundai TB
luego del minuto 4 esta la explicacion de la resonancia con la ECM (daña las pistas se explico antes)
Exactamente.
None of these electronic or smog problems were there when you had mechanical and people were allowed to tune a motor
I want the one that is under battery for dodge ram hemi 1500 on 2005
Its aelectrical throttle under battery
It runs the cruise and gas throttle
Ok
