What does code p0446 mean on a 2001 Buick Centry?


P0446 Evaporative Emission Control System Vent Control Circuit Malfunction The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP). The description of the fault varies between different car manufacturers, but one thing is common, the code P0446 doesn't directly point to a defective part; some testing might be required to pinpoint the faulty component. What can cause the code P0446: - faulty vent control valve - blockage at the vent hose, vent filter or vent control valve - open or short in the vent control valve circuit - bad charcoal canister - EVAP system leak - faulty EVAP system pressure sensor - bad vacuum switching valve (VSV) - stuck open purge valve (solenoid)

Hello there,my 2001 echo is lighting up trouble codes p0440 p0441 p0446; how and where should i start?


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

    Got a code of p0446 on my 95 gmc jimmy 4wd. what is it and how do i fix it? When do i know it is solved? Or what should i look for?


    P0446 - Restricted/Blocked EVAP Vent Path.

    The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

    Possible Causes:
    Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.

    Possible Solutions:
    - Clean the EVAP canister vent hose assembly.
    - Replace the EVAP canister vent valve & solenoid.

    The DTC will clear once the issue has been resolved or you can clear the code with a GM approved scanner. Do not clear the code before the issue is corrected otherwise the light will keep coming on.
