Function, maintenance and classification of throttle position sensor

With the popularity of automobiles, throttle position sensors have been widely used. Today, Bian Xiao will introduce the throttle position sensor to you. What is a throttle position sensor? The so-called throttle position sensor is a device used to detect the working state of the engine.

Firstly, the function of throttle position sensor is introduced. Our so-called throttle position sensor is commonly known as throttle switch. The main function of the throttle position switch is to detect which working state the engine is in (generally, the engine has two working states, idle working or load working). When our resistance shaft is linked with the throttle, there will be full open contacts and idle contacts. When the accelerator of our car is in the idle position, the resistor will send the information of idle working to the computer. When the throttle valve appears in other positions, the idle speed at this time is converted to the load state. The resistor will send a signal to the computer indicating that the engine is now under load, and the rate of change will be identified according to the corresponding electrical signal. These data will be fed back to our driver, and the driver will correct the direction and increase or decrease the fuel intake according to these detection information.

Secondly, the application and maintenance of throttle position sensor are introduced. There are two contacts on the throttle position switch, one is the idle contact and the other is the load contact. These two contacts control the engine speed respectively, and adjust the throttle accordingly according to the engine speed, so as to correct the engine speed. However, after long-term contact with oil, friction will occur, reducing the sensitivity of contact. We can't make corresponding fine adjustments, which reduces the comfort of the car. Under normal circumstances, we will wipe it with cleaning agent, observe the wear degree of the contact, and repair it according to the wear degree to maintain the comfort and stability of the car.

Finally, the classification of throttle position sensor is introduced. Throttle position sensors are generally divided into linear output throttle position sensors and dry output throttle position sensors. Linearity: generally used in large vehicles (the body of large vehicles is more stable than long linear transmission information) and drying: generally used in small cars (the short and dry body of small cars can meet data transmission).

The above is Bian Xiao's personal understanding of the throttle position sensor. I hope everyone can maintain their vehicles in their daily lives and let them provide us with a comfortable driving environment. I hope the above content can help you.
