Positive Crankcase Ventilation Valve: Testing and Inspection
The technician should be aware that diagnosis and testing of the Positive Crankcase Ventilation (PCV) system should begin at the Powertrain
Management level, where testing begins with Diagnosis by Symptom, , and is narrowed to testing of a "specific" subsystem and it's related wiring and
components. Following the appropriate diagnostic routines may prevent misdiagnosis and unnecessary component replacement. Refer to Powertrain
Management/Testing and Inspection/Procedures.
