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.
