A loose gas cap will cause this code. Ensure the fule filler cap is on tight. Eventually the code will automatically disappear if that is the problem.

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code


Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

2003 DARANGO SLT 4.7 -2 WD, AUTO, 99K MILES, CODE PO441 WITH KEY


0441 the most common fix for this code in chrysler/dodge vehicles is to replace the leak detection pump / ldp -----other areas to check would be damage / restriction in evap line / canister---faulty purge solenoid or connection damage or resistance in line -bad vacuum switch

I have a 1997 caravan and i got a po441 code what


You will have to test the purge solenoid that vents fuel vapor to the charcoal canister ( or back into the engine ) with a multimeter, check for ohms resistance per values set by dodge, the values are in the haynes repair manual.

2003 toyota highlander OBD code's po442/po446/po441


if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal
