Common causes for codes p0441 - 2001 Chrysler 300M

code p0446 refers to evaporative emission (EVAP) system--vent control--circuit malfunction===causes wiring--EVAP canister purge valve--ECM
Code p0441 is evap system--incorrect flow detected==causes --hose connections --intake leak--EVAP canister purge valve
replace the purge valve as it is common to both codes
dodge code p1400 is related to a problem EGR system

The P0441 code means that the control module has detected a leak in the Evaporative Emission (EVAP). Loose fuel tank filler cap is the most common cause that triggers the P0441 code.

P0113 OBD II Trouble Code

https://www.obd-codes.com/p0441

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try: Common Chrysler fix - Replace Leak Detection Pump / LDP Repair damaged EVAP lines or canister Repair open or short in voltage feed circuit to Purge Solenoid Repair open in PCM purge command circuit Replace purge Solenoid Replace vacuum switch Repair restriction in Evap line or canister or soleniod Repair resistance in purge connector Replace PCM, as you haven't posted your vehicle make model year etc i've listed the most common faults, as you have tried a few of these i'd go for the open/short circuit to/from PCM , hope this helps these are a real pain to get to the cause at times

code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes

code p0129 refers to barometric pressure-two low===causes wiring---BARO sensor, ---mechanical fault
code p0441 refers to evaporative emission (EVAP) system--incorrect flow detected=== causes ---hose connection/s---intake leak--EVAP canister purge valve

replace the BARO sensor and the purge valve after seeing that the filler cap is on correctly.

P0441 JEEP - EVAP Purge System Performance
Possible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve Tech notes Loose or damage fuel tank filler cap may trigger the P0441 code

Did you have the codes erased after the repair ?
The evap system has several parts that could cause the code.
The system applies pressure to the fuel tank every few minutes and checks for leaks. If any are detected, or if the system will not hold pressure, the light comes on. A common problem is a faulty gas cap but I don't know if that will set a code 441.

the p0441 code has to do with the fuel i have heard of people simply replacing the gas cap or simply cleaning it to get the p0441 code to go away you may need a new cap thoe. the canister purge valve would need replaced if that dosent work. those are the most common fixes. i hope this info helps you

Most common problem causing this code is the purge solenoid. A quick smoke test will show if you have any leaks in the system. If no leaks and the fuel cap is installed properly it's the purge solenoid.
