Trouble Diagnoses For Abnormal Pressure (Part 4 Of 4):

Whenever system's high or low-side pressure is abnormal, diagnose using a manifold gauge. The marker above the gauge scale in the following table indicates the standard normal pressure range. Since the standard (normal) pressure, differs from vehicle to vehicle, refer to performance chart "Ambient air temperature-to-operating pressure table".
Pressure measurements are effective only when ambient temperature is in the range indicated under the Performance Chart.
