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.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the evaporator temperature sensor connector. 3. Measure resistance between terminal "+" and "-" of the evaporator temperature sensor.
Description The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperature.
