High Pressure Sensor / Switch: Testing and Inspection
Before performing diagnosis of the A/C high pressure switch, verify that the refrigerant system has the correct refrigerant charge.
For circuit descriptions and diagrams.
1. Disconnect and isolate the battery negative cable.
2. Unplug the A/C high pressure switch wire harness connector from the switch on the refrigerant system fitting.
3. On the four terminal A/C high pressure switch, check for continuity between terminals C and D. On the two terminal A/C high pressure switch,
check for continuity between both terminals of the switch. There should be continuity. If OK, test and repair the A/C switch sense circuit as
required. If not OK, replace the faulty switch.
