Measure the pressure of high pressure line by measuring voltage output between terminals No. 1 and No. 2.
2.
Inspect the voltage value whether it is within the specified range.
Voltage = 0.00878835 * Pressure + 0.5[PSIA]
3.
If the measured voltage value is not within the specification, replace the A/C pressure transducer.
Replacement
1.
Disconnect the negative (-) battery terminal.
2.
Recover the refrigerant with a recovery/charging station.
•
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work.
3.
Disconnect the A/C pressure transducer connector (A).
4.
Remove the A/C pressure transducer (B).

Be careful not to bend the liquid & suction pipe.
5.
Install in the reverse order of removal.
•
When installing, replace it with a new O-ring (A).

The evaporator temperature sensor will detect the evaporator
core temperature and interrupt compressor relay power in order to
prevent evaporator from freezing by excessive cooling ...
Replacement
1.
Loosen the wheel nuts slightly. Raise the vehicle, and make sure it is securely supported.
2.
Remove the front wheel and tire (A) from front hub.
