Description and Operation

Description and Operation

 Description

А/С pressure transducer convert the pressure value of high pressure line into voltage value after it is measured. By voltage value, the engine ECU controls cooling fan by operating it high speed or low speed. Engine ECU stops the operation of compressor when the temperature of refrigerant line is too high or too low to optimize air conditioning system.

Repair procedures

Inspection

1. Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals.

2. Inspect the voltage value whether it is sufficient to be regular value or

2. Inspect the voltage value whether it is sufficient to be regular value or not.

Voltage = 0.00878835 * Pressure + 0.37081095 [PSIA]

3. If the measured voltage value is not specification, replace the А/С pressure transducer.

Replacement

1. Disconnect the negative (-) battery terminal.

2. Recover the refrigerant with a recovery/charging station.

3. Disconnect the А/С pressure transducer connector (3P) (A).

Tightening torque: 10~12 N.m (1.0~1.2 kgf.m, 7.4~8.8 lb-ft)

CAUTION

CAUTION

Take care that liquid & suction pipe are not bent.

4. Installation is the reverse order of removal.

Evaporator Temperature Sensor

Description and Operation

 Description

The evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power in order to prevent evaporator freezing by excessive cooling.

Repair procedures

Inspection

1. Ignition "OFF".

2. Disconnect evaporator temperature sensor.

3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
