DTC B1436/36 Air Mix Damper Position Sensor Circuit (Driver Side)

DESCRIPTION

DTC Detecting Condition:

This sensor detection the position of the air mix control servo motor (air outlet damper) and sends the appropriate signals to the A/C amplifier assembly. The position sensor is built in the air mix control servo motor. The position sensor resistance changes as the air mix control 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 assembly. The A/C amplifier assembly reads the arm position with the input voltage from the position sensor.
