So my 2012 Dodge Caliber has just under 63k miles and is showing error code P0441 EVAP Purge System Performance, which according to my local Auto Part store could be the Fuel Vapor Leak Detection Pump at $34.99 or the Canister Purge Valve at $24.99 while both are fairly cheap I would like to know if either has a history of going bad so that I can address the most likely first. A bit of history on the car first it threw this code previously and went back off on two occasions now it seems it is on to stay.
