This may not turn out to be true all the time as the ac could have failed due to a fault in some other component. Again a factory scan tool is usually required to perform diagnostics on the system.

R134a pressure gauge chart this chart details how ambient temperature correlates with the system refrigerant charge pressure and how it affects high and low side psi readings. It can be used for recharging refrigerant or to diagnose an a c system based on pressure readings from your gauges. R 134a temperature pressure chart tabla de temperaturas y lecturas.

Many sources tell you to start your charge diagnosis by checking static pressure. There is a relationship between the pressure in the system and temperature. At idle condenser inlet temp 170 to 180 condenser outlet temp 135 to 150 usually.

Noise from the compressor usually means the compressor is on its way out. A temperature pressure chart can be used to compare the pressure of the refrigerant at a given temperature. It s a good starting point but you should never rely on static pressure readings as the sole indication of system charge.

Static pressure is the pressure with the sytem at rest. Air conditioning a c pressure diagnosis can also help pinpoint the concern with a malfunctioning system. Automotive ac pressure chart for air conditioning systems with r134a.

You can t really diagnose charge level in your car ac with gauges using static pressure. However knowing what the gauges say can be troublesome for some technicians.
