Throttle Position Sensor

The throttle position sensorresponds tothe accelerator pedal
movement. Thissensor isakind ofpotentiometer whichtrans-
forms thethrottle position intooutput voltage, andemits the
voltage signaltothe ECM. Inaddition, thesensor detects the
opening andclosing speedofthe throttle valveandfeeds the
voltage signaltothe ECM.
Idle position ofthe throttle valveisdetermined
by
the ECM
receiving thesignal fromthethrottle position sensor.Thisone
controls engineoperation suchasfuel cut.
