NG -- REPLACE AMBIENT TEMPERATURE SENSOR
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (AMBIENT TEMPERATURE SENSOR - A/C AMPLIFIER)
(a) Disconnect the A/C amplifier connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

HEATING / AIR CONDITIONING: AIR CONDITIONING SYSTEM: B1413/13: Evaporator Temperature Sensor Circuit
B1413/13 - Evaporator Temperature Sensor Circuit
DESCRIPTION
The evaporator temperature sensor is installed on the evaporator in the air conditioning unit to detect the cooled air temperature that has passed
through the evaporator and to control the air conditioning. It sends appropriate signals to the A/C amplifier. The resistance of the evaporator
temperature sensor changes in accordance with the cooled air temperature that has passed through the evaporator. As the temperature decreases, the
resistance increases. As the temperature increases, the resistance decreases.
The A/C amplifier applies voltage (5 V) to the evaporator temperature sensor and reads voltage changes as the resistance of the evaporator
temperature sensor changes. This sensor is used for frost prevention.
