The A/C Pressure Transducer (APT) converts the pressure value
of high pressure line into voltage value after measuring it. Engine ECU
converts the voltage value to control the cooling fan by operating it
in high speed or low speed. Engine ECU stops the operation of the
compressor when the temperature of refrigerant line is very high or very
low irregularly to optimize air conditioning system.
Inspection
1.
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.
