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.
Oil Specification 1. The R-134a or R-1234yf system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2.
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.
