What is the relationship between the idle contact idl and the power contact psw of the contact switch throttle position sensor and the load?

Hello. The comprehensive throttle position sensor has four lines, among which there is one more idle contact than our ordinary throttle position sensor. The so-called algebraic contact means that when the engine is idling, that is, when the load is small, the throttle opening is the smallest. The power connection is that our engine is stepping on the accelerator, and then our opening will increase. What about the power contacts? The signal generated by the signal will increase the voltage. In other words, the greater the load, the greater the signal generated by our power contact. I hope it helps you.
