What is the name of the throttle position sensor? What is the specification name of idle motor? (professional answer)

Throttle position sensor and idle motor. They are all standard names!

These two functions are different:

First, the throttle position sensor is used to detect the throttle opening, and then the signal is transmitted to the engine computer, which controls the fuel injection quantity.

Second, the motor is idling. This is a very old thing.

In the era of mechanical throttle, a cable directly controls the throttle opening at the accelerator pedal.

So when idling, the throttle valve is completely closed and the accelerator pedal is not stepped on. At this time, an intake passage is needed to maintain idle speed.

The passage is controlled by the idle motor and close to the throttle body. If the idle motor is blocked, it is easy to cause poor idle speed.

Finally, modern improvements were made, all of which were electronic throttles. The idle motor has disappeared. ...
