Code p0441 Information and Diagnostic AdviceDiagnostic code p0441 is set when the computer sees that there is not enough flow from the purge valve. Basically this means that there is a problem in the EVAP system (for more information on this see my write up on code p0440). The computer will command the purge control valve open and if it does not sense the right amount of vacuum then it will set this code. The most common cause for this code is: Faulty Purge Control Solenoid Some other things that can cause this code: Faulty Computer The first thing to check is for any hoses that might be damaged or disconnected under your hood. Other than that there is not much else that the average car owner can do to diagnose this problem. The diagnosis that would need to be done would include testing to see if the computer is commanding the purge control solenoid open and how much voltage is on the command wire. Then testing to see if the solenoid is opening correctly. Leave p0441 and go back to OBD Codes New! CommentsHave your say about what you just read! Leave me a comment in the box below. |
