DTC B1417/17 Rear Evaporator Temperature Sensor Circuit

DESCRIPTION

DTC Detection Condition:

The rear evaporator temperature sensor is installed on the rear evaporator. It detects the rear evaporator temperature. The sensor sends a signal to the A/C amplifier. The resistance of the rear evaporator temperature sensor changes in accordance with the rear evaporator temperature. As the temperature decreases, the resistance increases.As the temperature increases, the resistance decreases.

The A/C amplifier applies voltage (5V) to the rear evaporator temperature sensor and reads voltage changes as the resistance of the rear evaporator temperature sensor changes.
