Throttle Position Sensor: Description and Operation
Throttle Position Sensor At Wide Open Throttle And Closed Throttle Position
DESCRIPTION
The throttle position sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position
into output voltage, and emits the voltage signal to the ECM. In addition, the sensor detects the opening and closing speed of the throttle valve and
feeds the voltage signal to the ECM.
Supply Voltage / Valve Opening Angle
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine
operation such as fuel cut. On the other hand, the "Wide open and closed throttle position switch", which is built into the throttle position sensor unit,
is not used for engine control.
