Description
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 at high speed or low speed.
Inspection
1.
Turn the ignition switch OFF.
2.
Disconnect the temperature control actuator connector.
3.
Verify that the temperature control actuator operates to the
warm (Driver's side) or cool (Passenger's side) position when connecting
