How Electronic Throttle Actuators Work

Look inside an electronic throttle actuator and learn how the ECU controls and monitors the position of the throttle.

[@loreadaauto]

The visuals and explanations helped me understand how the actuator works and how it communicates with the ECU. Overall, it was a great educational video on electronic throttle actuators. Thank you for sharing.

[@nosuchthing4789]

Yup, very nice and a complete video. It is best to see the waveforms to understand it completely. Thanks for sharing!

[@kameishagreenunapologetica8210]

Wow great video and good insight! I truly understand those parts and how they work now💪

[@BobMaksymchuk]

Great video! Thank you so much. Very helpful.

[@wb4245]

Excellent, Excellent video!

[@PanRaf2012]

Good job. Thank you!

[@conorosullivan6513]

Thank you for sharing Justin. Very educational video I have to say. Really helped me understand the problem I am having with my car at the moment.

[@delightmakuku3305]

this is exactly the information i've been looking for ...thanks for sharing

Great video!!

[@mogtabaa5586]

thank you for sharing your engineering knowledge.great help..

[@kenlow4028]

Thank you so much for the technical information, This looks like fly by wire

[@mansourtabaie2573]

Great job.

It’s rest position is just a default position, so if there’s a fault with the throttle body you should still be able to limp home.

[@redinstrumental7535]

I did

[@garnetacealbright]

Full marks man now I understand it, I thought it was controlling the duty cycle of the motor but it is putting out 2 voltages to the motor like 12 and 10 to get it to open/close, my ECU is still not able to stroke the throttle flapper though, everything tested good, the pot and the motor, even the throttle motor relay is working. Do you know of any software that I could use to override (stroke) the throttle body motor?

P1683 HONDA - Throttle Valve Default Position Spring Performance Problem Can u help me about this… thanks much appreciated… Thanks for your video…

[@joseapduhan2321]

You can open and closed the round metal inside the throttle body right coz i just removed mine and it will only open it wont closed. It will closed if i will removed the top gear. Thanks

[@S.khan.123]

I spray throttle cleaning spray inside throttle body means inside gear spring assembly,any problem will occur?

Hello i have an issue with my honda Crv 2013 and its P1683… P1683 HONDA - Throttle Valve Default Position Spring Performance Problem

[@giantkilla_]

Can you do the same test with the positive and negative using the connectors that are on the black plastic part where the wiring harness connects?

[@JustinMillerAutomotive]

Yes, but you run the risk of damaging a computer if you do that while it is plugged in. I would recommend unplugging the connector, the jumping to the terminals on the throttle body (keeping the rest of the harness isolated).

[@sukhoy]

So this one doesn't use a stepper motor. I've seen others that do.

[@MosesIvlerMiracleBabyVlog]

It’s also says that // Powertrain, MFG, computer output circuit, Fault : 83 What’s does it mean? Thank you 🙏

[@JustinMillerAutomotive]

I wish I could diagnose it from a distance, but I can't. It would require some electrical testing - preferably with a lab scope. You could have a faulty throttle body or there may be an electrical issue with the sensor, the wiring, or even the computer.

[@DJ-tn7vj]

I think this is a throttle for a diesel vehicle. Where you need as much air to enter the vehicle at start up for compression. In comparison to a gas vehicle. I could be wrong.😁

[@robertmullen2480]

Justin really like your videos thank you...... on a side note having the throttle defaultto wide open is absolutely rediculous and crazy , dont understand the thinking here?? GM or Ford why is the spring holding it open ?? this is insane

[@ohenekwasi1404]

[@MohammedAli-bk7kh]

you are using a throttle fos deseil vehicle, gas engine has throttle closed

[@JustinMillerAutomotive]

This throttle is from a gasoline engine.

[@austinsquires8047]

would much rather watch this for 7 minutes than go through a electude module that easily takes double if not more time to teach me less. All the while making me think I'm mentally incapable of answering any of the questions they ask but never really provide the actual information needed to answer correctly.
