Question about Chevrolet Equinox

1 Answer

What do we do when the computer error code 0446 "purge vent solenoid defective" comes up at AutoZone? Is this a wiring issue or cannister problem. Understand what the solenoid does but how do we go about resolving issue? Am I damaging my vehicle by driving with this problem? (Chevy Equinox 2005)

P0446 could be a bad purge valve, bad ecm, or wiring between. the only way to know is to have a mechanic diagnose it. It needs to be repaired if you want the engine light off. If you let it go, the ecm cannot tell you if other problems are happening because the light is already/still on.

Is there a fuse for the vent solenoid? getting P0449 code but vent is good.


code p 0449 refers to evaporative emission (EVAP)system, vent valve ---circuit malfunction===causes --wiring ---EVAP cannister purge valve ---ECM
check the wiring for breaks , bad connections
replace the purge valve
the vent valve is part of the purge system of the EVAP system( fuel system)

Code po446 what is it


Its what is called the EVAP. system the code is for the vent solenoid .Gas vapor in a vacuum is drawn from the fuel tank when this vent is commanded to be open drawn into a canister filled charcoal and stored until the canister purge solenoid is commanded to open .
This happens when the engine speed is at a higher RPM level and is supposed to send the vapor to the engine to be burned instead of VOC'S going into the atmosphere .But its a crazy lie the last time I filled up more VOCS got into the atmosphere then a gas tank vent could do in 6 month or so .
You can try cleaning the filter in the vent solenoid it might work but the part is about 70 dollars its in the rear between the tank and the canister look for hoses .

I have a code P0449 on my 1999 chevy malibu 3.1


check engine light ison,autozone says code is P0449 this is whattheir ticket says:

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

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connevtor and wiring
3- Fuel saturated vapor canister
4- Failed EVAP vent solenoid

Code 449? what is this,anyone. tks


Code po449 is for bad  solenoid vent valve.After replacing the valve  check for the   12 volts at the "pink" wire.
This error relates too

The cost of the vent solenoid valve is near to 30 bucks. And the valve is located near the gas tank.

P0441 code means what ?


Evaporative Emission Control System Incorrect Purge Flow
The "EVAP purge flow" faults are issues between the carbon cannister and the intake. The EVAP leak detection generally concerns the fuel tank to carbon cannister plumbing.
A little background. The EVAP or evaporative emission system is a control system to keep vapors from evaporation in the fuel tank from getting into the atmosphere. The fuel tank is not vented, but rather the vapors are piped to the carbon cannister (usually located behind the pass. side front wheel) where the charcoal element absorbs the vapor. This is actually a vapor "storage" device. Under certain engine operating conditions, the ECU activates the Cannister Purge Valve (N80) which opens and allows the engine vacuum to **** the fuel vapors back out of the carbon cannister. This purges the vapor, allowing the cannister to absorb more vapor. This evap system has been on vehicles since the '70s.
As part of the OBDII standard effective for 1996 cars and newer, it was mandated that leaks in the systems must be detected and reported as a fault which will set the Check Engine Light (CEL). To detect leaks, the system is pressurized by a pump so that leaks can be detected by a lack of appropriate pressure in the system. If there is a leak, such as a cracked vent hose, loose (or leaky) gas cap, poorly installed or defective O-rings on the fuel level senders on the fuel tank, etc. a code will be set. On the cannister to intake side, leaks are detected by deviations in the idle control system. If you have leaks in the lines from the carbon cannister to the intake, intake leaks, a defective purge valve, etc you will often get purge flow faults.
My first recommendation is to closely inspect all the small vacuum lines connected to the intake manifold. The corrugated plastic lines are often the culprits, as well as the fabricate covered vacuum lines. Also consider replacing the gas cap.

Lexus 300 es code 0446


Code 0446 is evaporative purge and vent control malfunctions.

Typically it is a vacuum leak in the evaporative system hose, bad cannister, or bad vsv valve (vacuum switching valve) on the cannister.

To fix the issue, start by checking the vacuum hoses to the canister; if one is bad replace it. If not, inspect the vsv valve by un-hooking the vacuum lines one at a time and check for vacuum. Last inspect the canister for damage, or broken connections. Replace any and all damaged or malfunctioning parts.

I hope this helps you, and I wish you luck on your repair.

I did post this solution to your first request, I hope you get it this time.

I have fault code P0441 showing up on my 2003 Dodge Durango. Not sure what this code is, or how to correct it..


P0441--
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.

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

Here are a few solutions that should be followed to fix this issue.

* 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


Please rate and god bless:)
