Specifications ? Type: Negative Thermal Coefficient Type Temp.[(
Inspection 1. Turn ignition switch OFF. 2. Disconnect the E Module connector. 3. Measure resistance between sensor signal terminal and sensor ground terminal.
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the compressor model.
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.
