Throttle Position Sensor: Description and Operation
Fig. 25 Throttle Position Sensor
When in the idle position, contact is made between terminals 1 and 2 of the throttle position sensor, Fig. 25. At this time, terminal 30 in the
deceleration relay and terminal TRK in the time relay are grounded.
Once the throttle butterfly opens beyond 72°, contact is made between terminals 2 and 3, a ground signal is received from terminal TK in the AC
relay, and the electromagnetic clutch on the AC compressor is disengaged.
