What is the structure of the throttle sensor?

The structure of the linear output throttle position sensor is that two contacts (or contacts) are linked with the throttle shaft, and one contact can slide on a resistor, and the throttle position signal is converted into a voltage value VTA through the change of the resistor. When the throttle valve is completely closed, the other contact is in contact with the idling contact id 1. IDL signal is used to control fuel cut-off and ignition advance angle. The following is: 1. Throttle position sensor: Throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle or load condition, acceleration or deceleration condition. Essentially, a variable resistor and several switches are installed on the throttle body. 2. The rotating shaft of the resistor is connected with the throttle valve; The rotating shaft of the resistor is connected with the throttle valve and has two contacts: a fully open contact and an idling contact. When the throttle valve is in the idle position, the idle contact is closed and the idle working condition signal is output to the computer; When the throttle is in other positions, the idle contact opens to output voltage signals at different angles relative to the throttle, and the computer will identify the engine load according to the signal voltage value; According to the change rate of signal voltage in a certain period of time, whether it is an acceleration state or a deceleration state is identified. The computer corrects the fuel injection quantity or controls the fuel cut-off according to these working conditions.
