DTC B1433 AIR OUTLET DAMPER POSITION SENSOR CIRCUIT

CIRCUIT DESCRIPTION

Detection Item:

This sensor detects the position of the air outlet control servomotor and sends the appropriate signals to the A/C amplifier. The position sensor is built in the air outlet control servomotor. The potentiometer's resistance changes as the air outlet control servomotor arm moves.

It outputs voltage (5 V) that is input to terminal 1 (VZ) and terminal 3 (PT) via the variable resister, and then to the A/C amplifier. The A/C amplifier reads the arm position with the input voltage from the potentiometer.
