Refrigerant Pressure On-Vehicle Inspection (K9K Model)
1) Connect manifold gauge to A/C system, and then operate A/C system.
2) Check output voltage for refrigerant pressure sensor (1) between GRY and BRN/WHT wire terminals, and then compare measured voltage with specified voltage in the graph.
If it does not show such characteristic as shown in the graph, replace refrigerant pressure sensor with new one.
