Specification Item Specification Coil Resistance (Ω) 6.0 - 7.0 [20°C (68°F)]
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the OCV connector. 3.
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.
Inspection 1. Emit intensive light toward the photo sensor using a lamp, and check the output voltage change. 2. The voltage will rise with higher intensive light and reduce with lower intensive light.
