System Overview Parkin Distance Warning (PDW) is an electronic driving aid that warns the driver to be cautious while parking or driving at low speed.
Removal 1. Remove the bumper cover. (Refer to Body - "Front Bumper Cover") 2. Disconnect the connector (A) from the PDW sensor.
Replacement 1. If the compressor is marginally operable, run the engine at idle speed, and let the air conditioning work for a few minutes, then shut the engine off. 2. Disconnect the negative (-) battery terminal.
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 high speed or low speed.
