DTC B1433/33 Air Outlet Damper Position Sensor Circuit

DESCRIPTION




DTC Detecting Condition:




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

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

It outputs voltage (5 V) that is input to terminal 2 (VZ) and terminal 3 (PT) via the variable resistor, and then to the A/C amplifier assembly. The A/C amplifier assembly reads the arm position with the input voltage from the position sensor.
