Instructions (R-134a) When Handling Refrigerant 1. R-134a liquid refrigerant is highly volatile. A drop on the skin of your hand could result in localized frostbite.
Component Location Index Engine Room 1. Service port (High pressure) 2. A/C pressure transducer (APT) 3. Service port (Low pressure) 4.
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.
