I got the code 0111. Diagnostic Trouble Code 0111 is detected when ...
- EVAP control system does not operate properly.
- EVAP control system has a leak in the line between intake manifold and EVAP control system pressure sensor.
I have checked the car. The part in the picture does not work properly. It is black plastic box with 3 hoses attached on it. It allows the fuel vapor get into engin to burn. Normally the vapor can not flow between each hose. Only when the thin hose get vacuum, the vapor can flow betwen the two thick hoses. If it does not work properly, the fuel vapor will leak and the car will have a bad gas milage. Anyone knows the name of it and where I can order it?

 

From the stickies:

- EVAP control system has a leak in the line between intake manifold and EVAP control system pressure sensor.

Possible causes include ...
- EVAP canister purge volume control solenoid valve stuck closed.

This is a "jackpot" code. It points to so many possible causes as to be almost useless. It may be accompanied by another DTC which is more specific.
