DESCRIPTION
This sensor detects the position of the rear air mix control servo motor (water valve servo motor) and sends the appropriate signals to the A/C amplifier. The position sensor is built in the rear air mix control servo motor (water valve servo motor).
The position sensor's resistance changes as the rear air mix control servo motor valve 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 valve position based on the input voltage from
the position sensor.

Result
2 INSPECT REAR AIR MIX CONTROL SERVO MOTOR (WATER VALVE SERVO MOTOR)
(a) Remove the rear air mix control servo motor (water valve servo motor).
(b) Disconnect the connector from the rear air mix control servo motor (water valve 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.
HINT
Standard resistance
(e) As the rear air mix control servo motor (water valve servo motor) moves from the cool side to the hot side, the resistance decreases gradually without interruption.
3 CHECK HARNESS AND CONNECTOR (REAR AIR MIX 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.
Standard resistance
REPLACE A/C AMPLIFIER
