DTC B1423/23 Pressure Sensor Circuit

DESCRIPTION

DTC Detection Condition:




This DTC is output when refrigerant pressure on the high pressure side is extremely low (0.19 MPa (2.0 kgf/sq.cm, 28 psi) or less) or extremely high (3.14 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 a refrigerant pressure signal to the A/C amplifier. The A/C amplifier converts this signal to pressure according to the sensor characteristics to control the compressor.
