Yep the P0441 is : The evaporative emission control bad purge flow. You wont be able to run the component test for this issue without a good scan-tool of component tester. It may have to do with the flow control valve. It should be located next to the charcoal canister.

P0129 and p0441 x2


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.

P0544 Code and problems with my Mechanics!


There is no code P0544 , maybe you mean P0455 ?
The control module tests the evaporative emission (EVAP) system for a large leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the EVAP system vacuum level. When the conditions for running are met, the control module commands the EVAP canister purge solenoid valve OPEN and the EVAP canister vent solenoid valve CLOSED . This allows engine vacuum to enter the EVAP system. At a calibrated time, or vacuum level, the control module commands the EVAP canister purge solenoid valve closed, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum level. If the system is unable to achieve the calibrated vacuum level, or if the vacuum level decreases too rapidly, this DTC sets.

It's called EVAP purge solenoid , the front one . An your Mechanic is probably not full of it . You need to know how the system works . If the computer set's a code for that system , it will not test it again till it's fixed an sometime other problems come up . After he fixed the first problem he should have told you that after a day or two or a couple of key cycles , starting the car cold till warm an a cold start again , sitting over night , 8 hours . Then the computer will retest the system . An other codes may set . Before putting blame , you should have to read about OBD 2 emissions , before being able to have a vehicle .

Got a P0456 engine code. Also leaking about 1/2 cup water overnight under the engine area.


You have to smoke test the evap system & use a scan tool
& follow trouble charts to diagnose

That has to be done by a repair shop--- otherwise you just throwing
parts at it

Po441 on dodge stratus


Evap Emissions Problem. Specifically Purge Flow. Check to make sure your gas cap is on tight. Disconnect negative terminal on battery, drive up to 50 miles, if code comes back. Replace Evap Purge Canister.

The engine light wont turn off so I was told it was an evap leak but I dont know where to find it


Check the next diagram (click over image for zoom)...

zjlimited_1121.jpg

Fig. Showing location of (1) Evaporative Emissions (EVAP) Canister Purge Solenoid and (2) Exhaust Gas Recirculation (EGR) Valve

Large Leak Test
This tests for large leaks and blockages in the EVAP system. The control module will command the EVAP vent solenoid ON, closed, and command the EVAP purge solenoid ON, open, with the engine running, allowing engine vacuum into the EVAP system. The control module monitors the fuel tank pressure (FTP) sensor voltage to verify that the system is able to reach a predetermined level of vacuum within a set amount of time. The control module then commands the EVAP purge solenoid OFF, closed, sealing the system and monitors the vacuum level for decay. If the control module does not detect that the predetermined vacuum level was achieved, or the vacuum decay rate is more than a calibrated level on 2 consecutive tests, a DTC P0440 will set.

Purge Solenoid Leak Test
If the EVAP purge solenoid does not seal properly, fuel vapors could enter the engine at an undesired time, causing driveability concerns. The control module tests for this by commanding the EVAP purge solenoid OFF, closed; and vent solenoid ON, closed; sealing the system, and monitoring the FTP for an increase in vacuum. If the control module detects that EVAP system vacuum increases above a calibrated value, DTC P1441 will set.

Small Leak Test
If the large leak test passes, the control module will test for small leaks by continuing to monitor the FTP sensor for a change in voltage over a period of time. If the decay rate is more than a calibrated value, the control module will rerun the test. If the test fails again, a DTC P0442 will set.


Hope this helps.

The check engine light came on & I went to autozone & they said the code was P0441 - EVAP emission control system purge flow fault, the woman said she had never seen that & that I should call...


This code does cause any dangerous condition, read what it means below plus possiable solutions.

P0441 - Evaporative Emission Control System Incorrect Purge Flow


Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors 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
- Leak is in vacuum line between intake manifold and purge control valve. Possible solution - Retight or replaced fuel tank filler cap
- Replaced damage or leaking EVAP canister

Engine light on diagnosed PO44O dodge said probably the purge control solonoid. where is this located on a 2004 dodge neon?


Try checking the gas cap first off. 95% of the time, an EVAP code, (purge solenoids, or any EVAP code) could be caused by a lose gas cap, or a defective gas cap.

And I know on SOME neons, the evap canister purge solenoid is located on a bracket attached to the air cleaner. Hope this helped.

My 2005 neon failed emissions. It gave me a codes 0441. What excatly does that define?


Trouble Code: P0441 (2.0L L4 VIN C Auto)
EVAP Purge Flow Monitor Fault Print this code dataprint_icon_codes.gif Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
Engine at idle speed in closed loop for 200 seconds, BARO Sensor signal less than 8,000 feet, ECT Sensor more than 160ºF, no Low Fuel, MAP Sensor signal less than 23.7" Hg, and the PCM did not detect any purge flow through the EVAP system during this test.

Possible Causes:
  • EVAP purge solenoid vacuum line loose, leaking or restricted
  • EVAP purge solenoid stuck leaking, stuck open or stuck closed
  • EVAP purge vacuum line to canister leaking or disconnected
  • EVAP canister leaking, damaged or has failed

Error code p 0441


P0441 Evaporative Emission Control System Incorrect Purge Flow OBD-II Trouble Code Technical Description Evaporative Emission Control System Incorrect Purge Flow
What does that mean? This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system
. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
copyscape.gif Symptoms Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes A code P0441 could mean one or more of the following has happened:
  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
Possible Solutions 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
