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 auto defogging connector.
3.
Verify that the auto defogging actuator operates to the open
position when connecting 12V to terminal 3 and grounding terminal 4.
