B1423 TOYOTA Description

This Diagnostic Trouble Code (DTC) is output when the refrigerant pressure is either extremely low (0.19 MPa [2.0 kgf/cm2, 28 psi] or less) or extremely high (3.14 MPa [32.0 kgf/cm2, 455 psi] or more). The air conditioning pressure sensor, which is installed on the pipe of the high-pressure side, detects the refrigerant pressure and sends refrigerant pressure signals to the air conditioning amplifier. The air conditioning amplifier determines the pressure from the signals in accordance with the sensor characteristics and controls the compressor accordingly.
