Throttle Position 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 MT 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 volume control solenoid valve when the throttle position sensor is
malfunctioning.
