DTC 32 AIR INLET DAMPER POSITION SENSOR CIRCUIT

CIRCUIT DESCRIPTION

Detection Item:

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

It outputs voltage (5 V) that is input to terminal 3 (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 position sensor.
