Can a Honda throttle body be cleaned and reset?
This article pertains to Honda throttle body cleaning and a Honda throttle body reset. All electronic throttle bodies accumulate carbon buildup on the throttle plate and bore—the Honda throttle body is no exception.
What’s the best way to clean a throttle plate?
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. Also, never use abrasive scrubbing pads or brushes to remove the carbon buildup.
What causes carbon build up on Honda throttle body?
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 does the throttle plate work on a Honda?
At idle, the computer commands the throttle plate to crack open slightly, much like the old carburetors. This feature eliminates the need for an idle air bypass valve. When the engine is off, the throttle plate is fully closed. That’s where the carbon buildup becomes a problem.

How to fix high idle after throttle body cleaning?
The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes. Then turn on your a/c with blower in high position for three minutes. This should fix it.
What’s the best way to clean a Honda Civic?
Easiest way of doing it is: put the e-brake on, turn off headlights, radio, and A/C, then start the car and let it idle for 5-10 mins until it gets to operating temperature. Drive the car normally for the next 3-4 driving cycles and you should be good. If not, you will have to get a TPS calibration with a scantool.
Why did Honda change the throttle body for fuel injection?
When carmakers switched to fuel injection, the purpose of the throttle body change to operate more like an air valve, allowing more air into the intak manifold as you put the pedal to the metal. To provide air at idle, carmakers installed an idle air bypass valve that allowed air to flow around the closed throttle plate.
When do I need to clean my throttle?
Don’t get me wrong, clean parts are usually working parts, but in the case of the throttle, I only recommend cleaning the throttle body if you notice your gas pedal sticking or hanging up when you use it. Your intake gets dirty because of one main reason: the PCV (positive crankcase ventilation) system.

What causes a throttle body to go bad?
A potentiometer sits on the throttle gear and returns signals to the computer through the sweeps on TB cover. Common failures are the swept area of the potentiometer getting wear marks in them, the sweeper arms breaking down, and the plastic teeth breaking or wearing off of the gears. Loading…
