Now the LP and HP gauge readings need to be considered. To determine failures, the gauges’ indications must be referred to a table with R134a operating pressure values for HP and LP.One of the first refrigerants to go was our friend R-12. At this point in time, in the early 1990’s, R-12 had seen the majority of it’s usage in automobile air conditioning. R-12 was banned in new automobiles and was replaced with by the HFC refrigerant we all know today as R-134a. Now, there are still some R-12 applications out there today.Diagnosis of R1234YF systems is different and not covered in this article. Older systems use R12 and while the pressure varies slightly from R134A, the principles are the same. A refrigerant gauge set will have two gauges.

Below the calculator is an approximate chart relationship of temperature to pressure.We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent …The Pressure/Temperature hart indicates the pressure and temperature relationship for three automotive refrigerants. Vehicles with a model year 1994 and earlier most likely use R-12 refrigerant. If you are not the original owner of the vehicle, however, be sure to check. Some owners have retrofitted R-12 systems to use the later R-134a. Resetting the low-tire light on the Subaru Outback will turn the low-tire-pressure light off.
