Description
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.

Inspection procedure



Hint:
*: If the ambient temperature is higher than usual but cooling is sufficient, bubbles in the sight glass are permissible.


Ok: the display is as specified in the normal condition column.

Then connect the voltmeter's positive (+) lead to terminal 2 and the negative (-) lead to terminal 1. Measure the voltage.
Ok: the voltage changes in accordance with the refrigerant pressure as shown in the graph.
