NOTICE:
If refrigerant pressure on the high pressure line is excessive, this DTC will be set. Therefore, it is necessary to measure the voltage
over a period of time (approximately 10 minutes) because this DTC may be set after the A/C has been operating for a while.
HINT
When the outside air temperature is low (below -1.5锟斤拷C (29.3锟斤拷F)), the compressor stops due to signals from the ambient
temperature sensor and the evaporator temperature sensor to prevent the evaporator from freezing. In this case, perform the
inspection in a warm indoor environment.

B1423/23 - Pressure Sensor Circuit
DESCRIPTION
This DTC is output when refrigerant pressure on the high pressure side is 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 A/C pressure sensor is installed on the high pressure line. It detects refrigerant pressure to output a
refrigerant pressure signal to the A/C amplifier. The A/C amplifier converts this signal to a pressure value according to the sensor characteristics to
control the compressor.
