TROUBLE DIAGNOSIS FOR ABNORMAL PRESSURE
Whenever system's high and/or low side pressure is abnormal, diagnose using a manifold gauge.

The marker above the gauge scale in the tables indicates the standard (normal) pressure range.

Since the standard (normal) pressure, however, differs from vehicle to vehicle, refer to "Ambient Air Temperature-to-Operating Pressure Table ".
