I have Aveo 2009 1.6 LXV with ecotec engine and e83 ecu. I found the error No. P0449. When I checked the circuit, I found that the the plug only is attached to the vent valve and the whole circuit was cut out. The problem now, I need the wiring diagram of the circuit or the ecu pinouts to solve this problem.
Really I am in urgent need for that and I seeking your help.
Thanks in advance.

Can you elaborate on what you mean the whole circuit is cut out? The wires for that come out of the trunk on the passenger side iirc. Check to make sure you didn't cut or disconnect it.
There is a 20 cm wire with the plug attached to the vent valve, the wire cut from that point to the font. I want a picture to show the place in the front that I can connect the wire coming from the vent valve to the engine ecu?Quote:

The attached photo is what I have the solenoid and the vent valve in addition to the plug and 20 cm of two wires; the red is for electricity and I guess it goes to the fuse box the yellow one for signal and I guess it goes to ecm. I need to know the diagram of the yellow wire. I ask if that wire goes to another plug or goes to ecm directly and which pin number is assigned for it?
thanks in advance

Please anyone can help me, don't hesitate?
Thanks all of you. I reached the right wiring schematic of the evap sensor and it works.
