On a Dodge a lot of times this light comes on because you are putting gas in the car or truck with it running, have someone with a OBD2 box clear the code and try this, when you open the gas cap with it running it sucks air and sets off the light due to a purge in the system. I hope this helps

What does this code P0441 mean for engine light on 2004 dodge ram 1500 truck?


2004 Dodge Ram 1500 Truck Code P0441 indicates that a part of the EVAP control system is no longer functioning 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 controlled 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.

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 solenoid Repair resistance in purge connector Replace PCM

I hope this helps.

97 dodge ram1500 5.9 Between 65 and 75mph truck makes a violent like shudder. Rpms stop about200 and check engine light comes on with code p0441. I know what the code is but no idea where too start. And...


code p0441 refers to evaporative emission (EVAP) system--incorrect flow detected== causes--hose connections---intake leak==EVAP canister purge valve
I would start at the purge valve because if the tank is not venting properly there will be either a pressure build up which will over fuel the engine ( too rich) or the fuel pressure will be too low (vacuum in the tank not allowing the pump to keep pressure up) which will result in random misfires.

Hi I have 4 engine codes in a 2003 Dodge Intrepid 3.5 p0770,p0441,p0841 andp1776.I need more insight. Thanks Kevin


Kevin, It sounds like you have several things going on. You first code P0770 did not pull up on my database,. The P0441 is for an evaporative leak in your fuel purge system. Vapors are continually pulled from the fuel tank on later model fuel injected vehicles. A leak in this system such as a damaged hose, loose gas cap, etc.. can trigger one of these codes.

Your last 2 codes are relating to a transmission solenoid fault. Hopefully, this will head you in the right direction.. Best of luck..

I have a 2003 kia optima and it failed the emissions and gave the p0441 code. what is the problem? Or the most common problem may be.


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

Chrysler intrepid 2003 obd 2 code P0441


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.

Check engine light on code p0441 dodge ram 1500 my 2007 dodge ram 1500 is puttering and acting like it wants to die out can you let me know what the problem is.


This trouble code is Evap Purge System Performance fault. 1) Check for a loose or missing fuel cap. 2) Check for a damaged or missing fuel cap seal. Recheck for other trouble codes. This fault wont cause the stumblering problem. It turns on the MIL lamp to say there leak in the EVAP system.

Code P0441


Code P0441 = evap code (auxiliary emissions control systems),You could try replacing the fuel cap first (make sure it has the double gasket), but most likely the charcoal canister has failed or you have a leak in a hose related to the evap system.
