So my check engine light turned on today while driving. (01-11) EVAP control system/Flow. I know this has been asked around a lot and I checked the FAQ and it's not there. What is this problem and how do I fix it. Thanks!!

Just got my handy dandy Haynes Repair Manual (6-21 Emissions and engine control systems), and IT says:
EDIT: IT Says you better Look on these forums harder, start by going to the 4th Gen Forums and finding the ECU Codes Defined Again << title of thread! your Code is there with everything that's in the Haynes Manual, but that's okay, maybe you're new.

Thanks for pointing out where to look. It says...

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.

Possible causes include ...
- EVAP canister purge volume control solenoid valve stuck closed.
- EVAP control system pressure sensor and its circuit.
- Loose, disconnected, or improper connection of rubber tube.
- Blocked rubber tube.
- Blocked or bent rubber tube to MAP/BARO switch solenoid valve.
- Cracked EVAP canister.
- EVAP canister purge volume control solenoid valve.
- Closed Throttle Position Switch.
- Improper connection of one-way valve.
- Blocked purge port.
- EVAP canister vent control valve.


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.



I resetted my ecu and it hasn't turned back on since. Do you think the problem is still there or should I fix it before the light turns back on; if ever?
