1.2L REVOTRON ENGINE 67 II. Purge Control Valve : Component Details : Purge Valve is a solenoid valve (Variable position), its opening is controlled by controlling the field current of the magnetic coil. Component Location : Preliminary Checks : 1. Loose or damaged connections between actuator and EMS ECU. 2. Check for back out of pins at both actuator and EMS ECU connector. 3. Check for damage of connectors at both actuator and EMS ECU end. 4. Check whether the actuator is stuck open/ closed - Mechanical failure. Connector View : Connector Details: Connector Description 1 Ground 2 Supply Component Specification : The Canister Purge Valve (CPV) meters the gas flow which is generated during regeneration of the activated carbon filter, utilized for fuel tank ventilation. The CPV is triggered by impulses. Duration and frequency are adjusted by EMS ECU depending on the load condition of the engine. Mounted on intake manifold by bracket Sensor Stand alone Diagnosis : Measure the resistance across the Purge valve terminals at room temperature; it should be 16+/- 2 Ohms.
