Pressure Switch Circuit

PRESSURE SWITCH CIRCUIT

CIRCUIT DESCRIPTION

The pressure switch sends the appropriate signals to the air conditioner control assembly when the air conditioner refrigerant pressure drops too low or rises too high. When the air conditioner control assembly receives these signals, it outputs signals via the Engine & ECT ECU to switch off the compressor relay and turns the magnet clutch off.
