Positive Crankcase Ventilation: Service Precautions

PCV Monitoring

OBD Exemption:

The systems are designed such that the connectors are fastened in a manner which makes it significantly difficult to remove. Disconnection between the
PCV valve and the intake manifold may cause the vehicle to stall immediately during idle operation or to detect a trouble code either for air/fuel
adoption or misfire.
