Throttle dashpot

The throttle dashpot, also known as the linkage damper, is located between the intake manifold and the air filter of the engine. It regulates the amount of air that enters the cylinders. The deeper you press the accelerator pedal, the wider the valve opens. This directly affects the combustion in the cylinders and the power of the engine. In diesel engines, the valve is always either fully open or fully closed, which maximizes the air supply.

A properly functioning throttle dashpot ensures precise airflow. This results in more powerful combustion and more efficient power delivery. Your vehicle accelerates more smoothly and responds more quickly to the throttle. 

A properly adjusted throttle valve improves fuel efficiency. Optimal airflow means your engine uses less fuel, which is good for your wallet and the environment. A stable airflow also prevents excessive wear and tear on engine components. It reduces stress on the cylinders and valves, which extends the life of your engine. 

A clean and properly adjusted throttle valve ensures immediate throttle response. Your vehicle feels agile and responsive, which is especially important when passing and cornering. 

How to replace a throttle valve damper

If you notice that your vehicle is less powerful, runs erratically or has poor response, have your throttle valve checked. If you prefer to do it yourself, here is a general a step-by-step plan:

Cleaning: Before you start, make sure you wear safety glasses and gloves. Make tinkering more enjoyable by using a cleaning cloth and a cleaning agent, such as brake cleaner. Dampen the cloth with the cleaner and use your fingers to open the throttle valve. You can then clean the inside of the housing.

Visual inspectionCheck the throttle valve for signs of wear, rust or contamination. Look for any cracks, loose parts or damage. 

Throttle position sensor: There is a throttle position sensor in the throttle body. This sensor measures the position of the throttle valve and sends this information to the car's on-board computer. Check that the sensor is properly connected and undamaged.
