Toyota Sienna Service Manual: Air Outlet Damper Position Sensor Circuit
DESCRIPTION
This sensor detects the position of the air outlet control servo motor and sends the appropriate signals to the A/C amplifier. The position sensor is built in the air outlet control servo motor. The position sensor's resistance changes as the air outlet control servo motor arm moves.
It outputs voltage (5 V) that is input to terminal 2 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.

INSPECTION PROCEDURE
1 READ VALUE OF INTELLIGENT TESTER
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position and turn the intelligent tester main switch on.
(c) Select the items below in the DATA LIST, and read the displays on the intelligent tester.
DATA LIST / AIR CONDITIONER 
OK: The display is as specified in the normal condition column.
Result 
2 INSPECT AIR OUTLET CONTROL SERVO MOTOR
(a) Remove the air outlet control servo motor.
(b) Disconnect the connector from the air outlet 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 outlet control servo motor moves from the FACE side to the DEF side, the resistance decreases gradually without interruption.
3 CHECK HARNESS AND CONNECTOR (AIR OUTLET 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.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain
types of severe impacts that may cause significant injury to the
occupants. They work together with the seat belts to help reduce
the risk of death or serious injury.
