Information - Throttle

The throttle is one of the most important elements of the intake systems of internal combustion gasoline engines. The throttle valve is necessary in order to regulate the amount of air that enters the engine for the formation of fuel-air mass.

Throttle valve is located in front of the intake manifold. The functioning concept of the throttle valve is very simple - the more the damper opens, the greater is the outlet cross section per unit time, respectively, more air goes through into the intake channel. More air means consequently, more fuel. The more fuel-air mixture there is in the combustion chamber, the higher power is generated.

The driver regulates the opening and closing of the throttle, every time he presses the gas pedal. The gas pedal is connected to the throttle. When the gas pedal is pressed, the throttle opens. The more pressing on the pedal, the more the throttle opens. If the pedal is pressed all the way, the throttle remains maximally opened. This is one of the few parts in a car that do not need a lot of attention. Basically, this part can last the entire period of its operation. However, while driving the throttle may get dirty. In time, dark oil stains appear on the walls of the throttle body, on the throttle itself and in its internal channels. There may be several causes of throttle pollution. The worst of them is the oily dust penetrating from under the valve cover through gases ventilation tube.

What you need to know about throttle valve replacement: lifetime limits, common defects and their signs, tips and recommendations

Throttle valve service life is not specified. It is replaced because of mechanical damages of the spindle, housing or return spring. The component breakdown can also be caused by the deposit which formed on it during car exploitation. In case of heavy soiling throttle valve cleaning can’t remove the problem: the component is to be replaced. The electromotor, drive and gears can break down in components with electric drive.

“Check Engine” indicator on the dashboard points at throttle valve defect. Unstable rpm at idle and jerks during driving may also indicate breakdown. Moreover, the engine can stall or start with troubles.

You can define throttle valve defects by computerized diagnostics at a service station. Replacement of the component is also recommended to be entrusted to professionals because demounting requires laborious removal of the throttle valve pipe. For this the air filter housing is demounted, then the throttle position sensor and the idle air control sensor are removed, the retaining bracket or screws are removed as well. Then the throttle valve gasket and the throttle valve itself are demounted. Unit assembly is performed in the reverse order.
