What does the purge control solenoid valve do?
In particular, the canister purge valve is an emissions control component that allows the engine intake vacuum to take the exact amount of fuel vapors from the EVA canister into the engine intake manifold. In newer model vehicles the purge valve is electrically operated solenoid controlled by the engine computer.
Can a purge control valve be cleaned?
if your going to clean the valve, you should also blow compressed air into the center opening on the carbon canister…… all the dust/dirt will come out of where the purge valve goes on the canister…. you should also clean the big diameter breather hose that hooks on the inside of the frame……. and also blow …

While you can still drive your car with a bad purge valve, you will only expose it to further damage not only to the EVAP system, but as well as to the other parts in your vehicle. The more you drive the vehicle with a bad purge valve, the more you will harm other parts. It is necessary to fix the problem eventually.
Can you install the purge control solenoid without the purge valve?
Yes, you can install the purge control solenoid without the use of the Purge Valve on the Diag B setups. A perfect example of a EVAP system that does not require the Purge Valve is the JDM Subaru ej207. This model still uses the same EVAP purge solenoid, but the mess of hoses is cleaned up considerably (only 2 hoses now).
Where is purge valve solenoid located on Subaru Impreza?
The fix was to replace Purge Valve control solenoid, P/N: 16102AA080 (16102AA490 for ’05-’07) – located under the intake manifold on the passenger side of the engine. This part is the same as on a ’97 Legacy that I recently had, so it’s a common part that Subaru has used for years.
Is the purge control solenoid still on the EJ255?
For some ej255 and ej257 models the round/black purge valve is still present, diag B. Whereas, some newer models replaced the valve with a second solenoid, diag C. Which hose goes where? Please see the diagrams below for your specific models.
Can a diagram a car run an EVAP purge solenoid?
Diagram A and B cars can be setup in the identical fashion, although it does not apply to diagram C cars. There does not appear to be an affect on performance, nor does it trigger a CEL. In short, all it takes to run the EVAP purge solenoid is the valve, 2 hoses, and 2 hose caps to block off the unused nipples.
