|Code B1413 Description

The No. 1 Cooler Thermistor (Evaporator Temperature Sensor) is installed on the evaporator in the air conditioning unit to detect the temperature of the cooled air that has passed through the evaporator and to control the air conditioner. It sends signals to the air conditioning amplifier. The signals change in accordance with the resistance of the No. 1 Cooler Thermistor (Evaporator Temperature Sensor). As the temperature decreases, the resistance increases. As the temperature increases, the resistance decreases. The air conditioning amplifier applies a voltage (5 V) to the No. 1 Cooler Thermistor (Evaporator Temperature Sensor) and reads voltage changes as changes in the resistance of the No. 1 Cooler Thermistor (Evaporator Temperature Sensor). This sensor is used for frost prevention.
The Diagnostic Trouble Code (DTC) will be set when the Air Conditioning Amplifier Assembly detects an open or short in the No. 1 Cooler Thermistor (Evaporator Temperature Sensor) circuit.
