Throttle position sensor function, throttle sensor price

In short, the throttle position sensor is the "personal doctor" that monitors the throttle. As one of the most important sensors in the electronic control system, what are its functions?

The role of the throttle position sensor

Detect the change of throttle opening and judge the operating condition of the engine.It is mainly used in engine electronic fuel injection system and electronically controlled automatic transmission system. It converts the change of the throttle opening into an electric signal and inputs it to the electronic control unit.YuanOn the ECU, the ECU determines the operating conditions of the engine according to the throttle position signal, and then the computer corrects the fuel injection amount and ignition timing based on the information of these operating conditions, which is essentially a variable resistor.

How much does the throttle sensor cost?

Throttle sensor includes a Hall-type throttle position sensor (ToyotaCamry), sliding resistance throttle position sensor (BuickExcelle), dual variable resistance throttle position sensor (NissanTian Lai) And 4 kinds of structure types of switch electric shock type throttle position sensor. As for the price of the throttle sensor, it is related to the product brand, structure and applicable models. Some original imported products may cost several hundred dollars, but most of them are around one hundred dollars.
