Toyota Sienna Service Manual: Air Inlet Damper Position Sensor Circuit
DESCRIPTION
This sensor detects the position of the air inlet control servo motor and sends the appropriate signals to the A/C amplifier. The position sensor is built in the air inlet control servo motor.
The position sensor's resistance changes as the air inlet control servo motor arm moves.
It outputs voltage (5 V) that is input to terminal 1 and terminal 3 via the variable resistor, and then to the A/ C amplifier.
The A/C amplifier determines the arm position based on the input voltage from
the position sensor.

Result 
2 INSPECT AIR INLET CONTROL SERVO MOTOR
(a) Remove the air inlet control servo motor.
(b) Disconnect the connector from the air inlet control servo motor.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance 
(d) Measure the resistance according to the value(s) in the table below.
Standard resistance 
(e) As the air inlet control servo motor moves from RECIRCULATION to FRESH, the resistance decreases gradually without interruption.
3 CHECK HARNESS AND CONNECTOR (AIR INLET CONTROL SERVO MOTOR - A/C AMPLIFIER)
(a) Disconnect the connector from the A/C amplifier.
(b) Measure the resistance according to the value(s) in the table below.
