The A/C pressure switch consists of a high-low pressure switch (A/C pressure switch A) and a middle pressure switch
(A/C pressure switch B).
• High-Low pressure switch
If the refrigerant pressure becomes too high (due to blockage or lack of airflow at the condenser), or too low (due to
leakage), the A/C pressure switch stops the A/C request a signal to the PCM and the compressor stops operating.
• Middle pressure switch
If the refrigerant pressure goes above or below 1,520 kPa (15.5 kgf/cm , 220 psi), the A/C pressure switch opens or
closes to signal the PCM to change the speed of the condenser fan and radiator fan (high-low).
