My second vehicle (not my F250 )is showing a check engine code which I don't understand. I'm hoping that somebody can explain and perhaps offer some fix suggestions. The code that came up was PO441 "EVAP emission control system purge flow fault" ? ANY ideas would be appreciated.

Thanks

 

What kind of vehicle is it?

 

sorry, Its my 10 year old (95) c220 mercedes.

 

Thats an OBDII code. The most likely cause for tripping that code is a loose or defective gas cap. Tighten the cap at LEAST 3 clicks after fueling, if you always do that anyway, replace it, it may be the cause. The next most likely cause is the vacuum hose to the EVAP canister is missing or cracked. After that, the purge or vent solenoid on the gas tank is defective and last, you may have a vacuum leak at the engine somewhere.
