Where is Beiqi Wangwei 306 valve sensor?

Beiqi Wangwei 306 valve sensor is located between the throttle and the intake valve, and most of them are installed on the intake pipe.

Idle contact IDL shall be carried out when the throttle valve is completely closed; When the throttle valve is fully opened or nearly fully opened, the full load contact PSW should be opened; At other openings, both contacts should be non-conductive. Otherwise, adjust or replace the throttle position sensor. The throttle of the automobile engine is controlled by the driver through the accelerator pedal, which changes the air intake of the engine and thus controls the operation of the engine.

Different throttle opening marks different working states of the engine. In order to meet the requirements of different working conditions, the electronically controlled gasoline injection system is equipped with a throttle position sensor on the throttle body. Throttle opening can be converted into an electrical signal and sent to ECU as the basis for ECU to judge the working condition of the engine.

Throttle position sensor function

The throttle position sensor is a throttle opening sensor or a throttle switch. Its main function is to detect whether the engine is in idle or load condition, acceleration or deceleration condition. It is essentially a variable resistor and several switches installed on the throttle body, and the rotating shaft of the resistor is linked with the throttle.

It has two contacts, a fully open contact and an idle 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 valve is in other positions, the idle contact is opened, and voltage signals with different angles relative to the throttle valve are output, and the computer identifies the engine load according to the signal voltage value.
