The A/C Pressure Transducer (APT) converts the pressure value
of high pressure line into voltage value after measuring it. By
converted voltage value, engine ECU controls the cooling fan by
operating it 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.
Replacement
1.
Remove the condenser.
2.
Remove the cap (B) on the bottom of the condenser with a L wrench (A).
Tightening torque :
2.7 ~ 3.1 N.m (0.28 ~ 0.32 kgf.m, 2.0 ~ 2.3 lb-ft)

Inspection
1.
Measure the pressure of high pressure line by measuring voltage output between terminal “1” and “2”.
2.
Inspect the voltage value whether it is sufficient to be regular value or ...
