Before the vehicle is started, the static system pressure should be read. Pressure values should be very nearly equal on both LP and HP gauges. The actual static pressure will depend on the ambient temperature. To ensure it is on the right level, refer to a static pressures table applicable for R134A refrigerant (N.B. not shown on this poster).

R1234yf runs just a bit higher pressures than r134a. May be a worn compressor or the control valve may have failed if it’s a clutch less type. A good scan tool can scan for ac fault codes, and even let you run the control valve to control the compressor.If the air conditioning isn’t blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan.
