P0441 Evaporative Emission Control System Incorrect Purge FlowOBD-II Trouble Code Technical Description Evaporative Emission Control System Incorrect Purge Flow This 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. Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light. A code P0441 could mean one or more of the following has happened: With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try: Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

It is always best to start simple on a lot of these things. This code indicates that somewhere in the evaporative system you have a leak that has set off the code. The gas cap is the most common culprit and that is where I would start. Buy a new gas cap and put it on. It may and should solve your problem. A lot of gas caps have rubber seals that do wear out over time. If this does not solve your problem simply use a search engine and type in p0441 a wealth of information will pop up. There are other possible causes and solutions but that's where I would start (with the gas cap)

i just replaced the timing belt, and asked the garage to look at the transmission for me because i thought i was experiencing some subtle shifting problems. they told me the transmission looked fine, but i needed a new filter and fluid. the engine light didnt turn on til a couple weeks later tho. does this sound like a new filter and fluid would fix this problem?

Most of the time they mean:
p0441 = Evaporative Emission System Incorrect Purge Flow
p0422 = Evaporative Emission Control System Leak Detected
(small leak)

You have a vacuum leak. This means that you will need to go through all of the vacuum likes and make sure they are connected and not broken. If they are broken buy new vacuum line, its like less and $1 per foot. In your case if you can I would replace all of the vacuum lines if they look cracked and old.
