That innovation which is achieved when innovators overlap layers of meaning in terms of its interpretation and creativity within a given context. With that in mind, a few days ago I read an article on the characteristics of independent artists (http://www.revistaarcadia.com/impresa/especial/articulo/el-momento-indep...
A canister purge valve is a solenoid valve controlled by the Power Train Control Module. The Power Train Control Module is a control unit that determines the ignition timing, fuel amounts and other parameters needed to keep the engine running.
Although generic, the specific repair steps may vary depending on make/model. The Evaporative Emissions System (EVAP) allows fumes from the gas tank to enter the engine to be burned, rather than vented into the atmosphere as an emission. The purge valve solenoid is supplied switched battery voltage. The ECM controls the valve by operating the ground circuit, opening the purge valve at specific times allowing these gasses to enter the engine. The ECM monitors the ground circuit as well, watching for faults.
