check for an emmission control system problem such as the heated cannister purge valve
Evaporative Emission System Incorrect Purge Flow
There is another problem. If the code is about the purge valve/system the problem could be a broken vacuum line or electrical connection.
you need to unhook your negative cable for a few that will reset>
Trouble code P0441 means:Evaporative emission control system incorrect purge flow
Trouble code P1441 means: EVAP System Flow During Non-Purge Conditions
Trouble code P0443 means: Evaporative Emission System Purge Control Valve Circuit
I had my check engine light come on in my 96 T'bird and I stopped at Autozone to get it checked. I got the P1443 error as well, and it said probable causes were: 1. Failed EVAP pressure sensor 2. Blocked hose between purge valve and FTP sensor 3. EVAP purge valve stuck closed I have read from others that say it could be just a cracked hose as well.
The canister itself probably needs to be replaced. The canister can become loaded with fuel over time, causing excessive fuel vapors to be sucked into the fuel delivery system.
It is... 31- Bad Evapotator purge solenoid circuit or driver
1. Disconnect the evaporative emission cannister purge valve electrical connector. 2. Remove the 2 fuel vapor lines and the evaporative emission cannister purge valve. 3. Put a straight through connector in place of the purge valve. 4. It would be better to replace the purge valve. Your car won't pass emissions without it. It will throw a code on the check engine light. 5. It's not a very expensive part.
P0441 EVAP Emission Control System Purge Flow Fault You can try cleaning the gas cap of any debris and reinstalling till you hear it click. Or it could be a bad purge solenoid. Or cracked or split lines in between in the evap system.
