Fuel Evaporative System

OPERATION
The purge solenoid valve is controlled by duty signals from the ECM to perform purging of the charcoal canister. Purging is done when these conditions are met:

1. After warm-up - Coolant temperature above 80°C (176°F)
2. Driving in gear
3. Engine speed more than 1,000 rpm
4. Accelerator pedal depressed (closed throttle position switch OFF)
5. Heated oxygen sensor functioning normally

SYSTEM TEST
1. Warm up the engine to normal operating temperature and let it idle.




2. Disconnect the vacuum hose from the solenoid valve and plug it as shown in the figure. Verify that no vacuum is felt at the solenoid valve.
3. If not as specified, check the solenoid valve.
