Specification ItemSpecificationCoil Resistance (?)30.0 ~ 35.0 [20
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the VIS valve connector. 3. Measure resistance between the VIS valve terminals 1 and 2.
Removal 1. Disconnect the negative (-) battery terminal. 2. Remove the photo & auto light sensor. (Refer to Windshield Wiper/Washer - "Rain Sensor") Installation 1. Install the auto light sensor. 2. Connect 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 at high speed or low speed.
