    P0440 code (Evap Malfunction) on 2001 Toyota 4Runner. Dealer told me I needed to have the charcoal canister replaced at a cost of $766 .... is this accurate, resaonable, guaranteed to solve the problem and make the engine light go off? I have felt the dealer has been less than honest in the past so I'm leery. Thanks ...

    I have a 1998 4runner and my check engine light turned on, I bought the OBD2 tool to figure out what the reason was for it turning on, same code appeared P0446 (evaporative emission control system vent control circuit malfunction) I am not sure how to resolve this problem as it states it is a circuit malfunction, I will give the other suggestions of buying a new fuel cap, and replacing the fuel filter ect. I was wondering if you proceeded with replacing the charcoal canister and if that was what the solution was it needed. I want to try and fix this myself and save on the cost. What was the outcome? Any suggestions?

Ok code PO446 is your vehicles EVAPORATIVE EMISSIONS SYSTEM the most common cause is the gas cap gor left offf and someone drove the car or the cap was not fully locked it will set the code
the other causes are leaking evaporative emission plumbing from the fuel tank to the engine compartment, someone changed the fuel pump and did not seal it properly,
Failure of a emission component in the evap system
The only way to diagnost these is an OBDII scan tool and a smoke machine the light will come on when the computer does its test of the system and there is a hole as small as .020"
1/20,000 of an inch !
The light can only be turned off by a OBDII scan tool

My 2006 Rav4 had the check engine light, 4WD light and VSC light come all on at once prior to my state inspection. It was placed on the state computer and the codes P043E, P043F, P2402, P2401 and P2419 all came up tell it was something to do with the R and R charcoal canister and filter, and fuel tank protector. I researched it and spoke with my dealership service manager, which he did not like the fact I researched but also was not very helpful in explaining until I really pushed the issue. From my research, this is a common problem with the Canisters and from speaking to another Toyota Tech. My car has 87, 000 on it so they won't even consider the Federal Warrantee on emissions...check your owner's manual, It goes to 80,000. You can buy the parts yourself at www.MetroToyotapartsnow.com for much less if you have a reputable mechanic to put them in.

My 06 cobalt has these codes can anyone tell me what they mean? Are they an expensive fix? p0446,p0455, p0172


code p0446 refers to evaporative emission (EVAP) system-vent control-circuit malfunction===causes --wiring--EVAP canister purge valve--ECM
code p0455 refers to EVAP system-large leak detected===causes --hose connections--intake leak--EVAP canister---EVap canister purge valve
code p0172 refers to system too rich, bank 1===causes intake blocked---EVAP canister purge valve--fuel pressure ---EGR system---injector/s ---ECM
because the EVAP purge valve appears in all codes I would be inclined to change that unit first the run the fault codes again

What does the code P0446 onn a 2002 2.4l 4 cylinder Dodge Stratus SXT mean?


Generally in google search type obd2 then po446 or whatever and an obd2 site will come up w specifics for that code. Vehicle specific generally doesnt matter. http://www.obd-codes.com/p0446 typing odb2 before the code is important to find the right site. Refer to link for specifics or search using that format I suggested.

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)
