Description Emissions Control System consists of three major systems. • The Crankcase Emission Control System prevents blow-by gas from releasing into the atmosphere.
Troubleshooting Symptom Suspect area Engine will not start or hard to start Vapor hose damaged or disconnected Engine struggles to start Malfunction of the Purge Control Solenoid Valve Rough idle or engine stalls Vapor hose damaged or disconnected Malfunction of the PCV valve Rough idle Malfunction of the Evaporative Emission Control System Excessive oil consumption Positive crankcase ventilation line clogged
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the auto defogging connector. 3. Verify that the auto defogging actuator operates to the open position when connecting 12V to terminal 3 and grounding terminal 6.
