check all hoses on vehicle especially around canister and make sure u have a factory gas cap
The canister purge solenoid is part of the evaporative emissions system. When it is commanded "open" by the PCM (computer), it allows fuel vapors in the fuel system to enter the engine. This solenoid basically acts as a valve regulating fuel vapor flow to the air intake system. By burning these vapors in the combustion process, the evaporation system helps to lower overall vehicle emissions. The solenoid circuit refers to the wiring used to control the function of this solenoid, and usually runs between the solenoid and the vehicles PCM.
any defect in the above mentioned canister working will cause your problem to happen
