DTC B1432 Air Inlet Damper Position Sensor Circuit

DESCRIPTION

Detection Condition:

This sensor detects the position of the air inlet control servo motor and sends the appropriate signals to the air conditioning amplifier. The position sensor is built into the air inlet control servo motor. The position sensor's resistance changes as the air inlet control servo motor arm moves.

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