DTC 31 AIR MIX DAMPER POSITION SENSOR CIRCUIT (PASSENGER SIDE)

CIRCUIT DESCRIPTION

Detection Item:

This sensor detects the position of the air mix control servomotor (air mix damper) and sends the appropriate signals to the A/C amplifier. The position sensor is built in the air mix control servomotor. The position sensor resistance changes as the air mix control servomotor arm moves. It outputs voltage (5 V) that is input to terminal 1 (VZ) and terminal 3 (PT) via the variable resistor, and then to the A/C amplifier. The A/C amplifier reads the arm position with the input voltage from the position sensor.
