DTC B1423/23 Pressure Sensor Circuit: Description
WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
This 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.
