Throttle Position Switch: Description and Operation
Throttle Switch (TS)
Throttle Switch
The Throttle Switch (TS) consists of 2-contact points (idle switch and wide open switch) and is connected to the throttle valve shaft. The throttle opening
in the idle state is detected by means of the idle switch, and the wide open state is detected by the wide open switch.
The ECM uses the "ON/OFF" signals from the throttle switch as one of the signals to control the fuel injector, ISC solenoid valve and EGR VSV (if
equipped).
