How Toyota fuel system works : Direct and Port

A Toyota master diagnostic technician explains how Toyota fuel system works. Including Port injection and Direct injection along with service tips.

In this new series on my channel I will take a monumental task of explaining the overly complicated engine computer control for OBD2 emission standard work. I will follow my channel's theme of simple but complicated to make this information easy to follow and understand for Toyota owners interested.

In part 3 of this series I will cover Toyota's fuel system. I'll start with fuel delivery we'll cover both return and returnless fuel pumps. Then we'll move to port injection and it's service tips.

Last but not least I'll cover direct injectors along with their construction, precautions and service tips.

Just re-entered Toyota world after 30 years. Bought wife a 2021 RAV4 . Your content and knowledge is second to none!!

The robustness of those port injectors are impressive. I recently replace all of the o rings and grommets on mine and other than dirt they looked like new. They're 22 years old and kept the valves shiny.

I always get excited when a new Car Care Nut vid shows in my notifications

This guy never ceases to amaze me. A must watch for Toyota owners or any car owner for that matter. More than halfway to 100K subscribers, let’s get

Toyota should donate you a million dollars for the value of your videos explaining the mechanical design of their own engines in a understandable way.

I did not know about the number on the Direct Injector. Never having worked on that system, I learned something new. Thank you for the video.

This Toyota class is educational and informative and professional . Thanks AMD for doing this i think ppl should know all this.

[Aamervip]

The most professional mechanic i ever seen.
Keep up the good work 💪

[hostilityy]

I clicked this video as fast as I could. This guy is so cool.

[aamiryousuf]

I always feel more educated and informed after watching your amazing videos.

Hats off to your great work. Keep it up!!!

Hyundai CRDi engines use both port and direct injection. Mine is 1.6L CRDi Turbo at 110, 000 miles and the lightest of grey soot on inlet valves and intake cover. Best of both worlds. My car "self" cleans the inlet side at low, medium running and converts to 100% GDI at WOT and high acceleration.

Even without a Toyota in the garage, learning a lot from these videos. Superb instruction highlighting potential DIY pitfalls (some very serious) and tips on spotting possible problems.

[jojormdabronx]

Learned something new I’ve never thought about. When a port injector’s seal goes bad, it lets in unmetered air into the combustion chamber.

AMD, you’re a savior. You are doing so much for the community.
Please try to make more live videos. Thanks.

I always learn something new when watching your show on YouTube.

I love how elements are ground side switch and pulse width modulated. Kirchoff's law states, how ever much the source voltage, it has to drop all of it at the component/element.
Very cool stuff! And then you have your power side switch where you have full voltage at the component that is being commanded...
Thanks for sharing your knowledge.

[devjyarn]

Your videos and content have been steadily improving over the last few months. Good work! Keep it up!

[zach]

Thank you AMD for your videos! I love how you break down mechanical concepts thoroughly. Learning a ton!

[on-site]

Life was. simpler economical with just port injection 😝. God bless

[handsomerob]

My word, you are knowledgeable! I could listen to you speak all day!
