Toyota Sienna Service Manual: Rear Air Outlet Damper Position Sensor Circuit

DESCRIPTION

Rear Air Outlet Damper Position Sensor Circuit

This sensor detects the position of the rear air outlet control servo motor and sends the appropriate signals to the A/C amplifier. The position sensor is built in the rear air outlet control servo motor.

The position sensor's resistance changes as the rear air outlet control servo motor arm moves.

It outputs voltage (5 V) that is input to terminal 2 and terminal 3 via the variable resister, and then to the A/ C amplifier.

The A/C amplifier determines the arm position based on the input voltage from the position sensor.
