Throttle Position Sensor/Switch: Description and Operation
COMPONENT DESCRIPTION
A closed throttle position switch and wide open throttle position switch are built into the throttle position sensor unit. The wide open throttle position
switch is used only for A/T control.
When the throttle valve is in the closed position, the closed throttle position switch sends a voltage signal to the ECM. The ECM only uses this signal
to open or close the EVAP canister purge control valve when the throttle position sensor is malfunctioning.
