Throttle Position Sensor – Working and Principle

The throttle Position Sensor controls the amount of flow of fuel given to the engine and how it controls depends on the amount of pressure given.

let’s look at a few prerequisites,
Throttle

Throttle Body

It is the part of the air intake system which controls the amount of air that gets inside the engine.
when we press the pedal gave the throttle body opens and more airflow into the manifold i.e, more fuel goes into the engine.

Position Sensor

This sensor gives the output signal based on the changing position/movement of an object, the output signal is then further processed.

Throttle Position Sensor(TPS)

It is a sensor used to monitor the air intake of an engine and is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle.
TPS is a variable resistor and switch. The main function is to detect if the engine is in idle condition or
load condition.

Principle of Throttle Position Sensor

When the throttle is pressed, the engine no more remains idle and the idle signal line is disconnected, a sliding varistor also follows the rotation, and the computer detects the voltage value, the data obtained, by comparison, analysis, and control of basic Injective amount.
as we know TPS works with an engine in Idle condition or Load condition, when the throttle does not have a load connected, the idle contact is opened, and the output is related to the voltage signal of different corners of the throttle, according to the signal.
The change in increase in the signal voltage in a certain period is an acceleration operating condition or a deceleration.
