Specification HO2S [Bank 1 / Sensor 1] [Euro-V] Item Specification Heater Resistance (Ω) 2.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the HO2S 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 • Before measuring the pressure of the refriferant line, check whether the refrigerant amount is charged in accordance with the specified charging amount.
