PFP:22620
Component Description
UBS00DZA
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 volume
control solenoid valve when the throttle position sensor is malfunc-
tioning.
