Trouble code

I have a trouble code that appeared (67 A/C press Sensor error). The scanner reads the correct highside pressure of 100 to 250psi. The books I have, don't indicate a "67" code for the AC. Obviously there's an error in the sensor reading check, but it's not noted in the book that I have found. Has anyone out there run across this code set?

DTC 67 is a/c refrigerant pressure sensor circuit.
Pressure sensor or a/c clutch circuit problem

67 will set when the PCM does not detect an a/c refrigerant pressure change of more than 9 psi when the a/c clutch has been cycled "off" for 10 seconds & then "on" for 10 seconds.

Book recommends inspecting harness & all associated connectors including the PCM for damaged or pushed out terminals..........
