Simple Evap Purge Valve Test

How to carry out a few simple tests on a EVAP purge valve solenoid (fuel tank breather valve) to see if it’s good or bad. The purge valve is part of the vehicle Evaporative Emission Control (EVAP) system which prevents fuel vapours in the fuel tank from escaping into the atmosphere. The EVAP system traps fuel vapours from the fuel tank and temporarily stores them in a charcoal canister. The tank breather valve is an electrically-operated solenoid, which is controlled by the ECM. When the engine is off, the purge valve is closed. When the engine is running and warmed up, the ECM pulses the purge valve open. The most common fault with the purge valve is when it sticks in either the open or the closed position. These are the main symptoms you will find with each:
Valve Stuck closed:
Engine light on
High exhaust emissions
Poor fuel economy
Petrol smell
Evap code P0496, P0497
Valve Stuck open:
Check engine light
Vacuum leak
Rough idle
Reduced fuel economy
Difficulty starting car after filling up
High exhaust emissions
Other fault codes could be P0440, P0441, P0443, P0444, P0445, P0446, P0447, P0448 or P0449

Where is this valve located on Peugeot 307 petrol 2006

[@ragbeara01]

Hi: As my original purge valve is no longer available (Peugeot 307 2002) I am using a valve from another year of same Peugeot model. However the connector is different so I cannot visually determine which of the two contacts is the positive. Is there a way to determine the positive contact without supplying voltage. I assume there is a diode in the circuit so can that determine the current flow, therefore the positive contact, using a meter: Thanks

[@martymartin2894]

Where is this located on the 307 thanks
