What is idle learn?

The idle learn procedure is for issues with problem idle components, IE mas air flow sensor, throttle body, i.a.c. valve, etc... when these go bad and need to be cleaned or replaced your pilot will most likely run awful or not at all once the problem is solved. This is because they are smart (the cars) and learn to compensate as best they can when the part is not feeding information it likes. Just replacing a battery won't usually cause the ECM to have created trim levels that are no longer helpful because there was an inop part in the air side of the manifold. Even a vacuum leak can wreak havoc on the poor thing. And this information is never put in an owner's manual because a large portion of drivers have no desire or chance at figuring any of this out and would be more dangerous than anything armed with technical information about their vehicle ? if your car idles and runs fine don't touch it. It will not cost you mileage as I said these are smart cars and are constantly operating as efficiently as possible with the information the sensors are feeding it. Peace

How much power does a cylinder make at full throttle?

Each cylinder is being fed some infinitesimally small amount of fuel so it can make 0.1% of the power it would make if it were running at full throttle. This makes individual cylinder-to-cylinder variations and tolerances that wouldn't be noticed at 10% throttle quite noticeable at 0.1% throttle.

How does an idle air bypass valve work?

To provide air at idle, carmakers installed an idle air bypass valve that allowed air to flow around the closed throttle plate. The fuel injectors provided the fuel and the bypass valve regulated airflow. But electronic throttle bodies don’t have an idle air bypass valve, and they don’t use a throttle cable. Instead, these are “fly by wire”.

Why does my Honda throttle body have carbon?

All electronic throttle bodies accumulate carbon buildup on the throttle plate and bore—the Honda throttle body is no exception. The carbon accumulates after the engine is shut down and is caused by hot oil and gas vapors rising to the top of the engine where they collect on the cooler throttle body.

How to clean throttle body?

Once off the engine, set the throttle body on a clean shop rag with the electronics facing up. Slowly open the throttle plate and begin cleaning by spraying the aerosol cleaner on a clean soft rag and wiping the solvent onto the throttle plate and throttle bore. NEVER spray the solvent directly onto the throttle plate.

Why don't you need to clean your throttle body?

You don’t need routine throttle body cleaning because your car’s computer is designed to adapt to normal carbon buildup issues. Pay for induction cleaning ONLY when you’ve got a performance issue like a rough idle or stumble on acceleration.

What is throttle plate opening?

throttle plate opening, it expects a certain amount of air to flow between the throttle plate and throttle bore. But as carbon builds up and reduces that space, the engine becomes air starved. The computer can detect the lower airflow based on inputs from the mass airflow sensor and commands an even larger throttle plate opening.

Can you spray throttle body cleaner on a throttle body?

Also, never use abrasive scrubbing pads or brushes to remove the carbon buildup. Never spray throttle body cleaner into an electronic throttle body while it’s still on the engine.

Can you use a spray cleaner on an electronic throttle body?

You can’t use that technique with an electronic throttle body, because the spray cleaner can flow along the throttle plate shaft and into the motor housing and circuit board areas, causing complete failure. Shops sell routine induction service as a way to boost profits. That’s a scam.
