DTC B1423 Pressure Switch Circuit

DESCRIPTION

DTC Detection Condition:

This DTC is output when refrigerant pressure is extremely low (0.176 MPa (1.8 kgf/sq.cm, 25 psi) or less) or extremely high (3.025 MPa (32.0 kgf/sq.cm, 455 psi) or more). The pressure sensor, which is installed on the pipe of the high pressure side to detect refrigerant pressure, outputs refrigerant pressure signals to the A/C amplifier assembly. The A/C amplifier assembly converts the signals to pressure according to the sensor characteristics to control the compressor.
