Description and Operation
• The Crankcase Emission Control System prevents blow-by gas from releasing into the atmosphere. This system recycles gas back into the intake manifold (Closed Crankcase Ventilation Type).
• The Evaporative Emission Control System prevents evaporative gas from releasing into the atmosphere. This system burns gas at appropriate engine operating condition after gathering it in the canister.
• The Exhaust Emission Control System converts the three pollutants [hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx)] into harmless substances by using the 3-way catalytic converter.
Troubleshooting
| Symptom | Suspect area |
| Engine will not start or struggle 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 |
