A/C Status, Input

A/C REFRIGERANT PRESSURE SENSOR
This signal is used by the Powertrain Control Module (PCM) to enable cooling fans when A/C refrigerant head pressure reaches about 1303 kPa (189 psi). If a fault is present in the A/C refrigerant pressure sensor circuit, a Diagnostic Trouble Code (DTC) 66 and 67 will set, and the A/C clutch would be disabled.
