It is not on the fuel tank it is on a small box located near the fuel tank or in some cases it is located on the vent line going to the vent boox

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 .

2007. What are the probable causes of DTC P0446?


DTC P0446: Evaporative Emissions (EVAP) Vent System Performance
Circuit/System Description
This DTC tests the evaporative emission (EVAP) system for a restricted or blocked EVAP vent path. The control module commands the EVAP canister purge solenoid valve Open and the EVAP canister vent solenoid valve Closed. This allows vacuum to be applied to the EVAP system. Once a calibrated vacuum level has been reached, the control module commands the EVAP canister purge solenoid valve Closed and the EVAP canister vent solenoid valve Open. The control module monitors the fuel tank pressure (FTP) sensor for a decrease in vacuum. If the vacuum does not decrease to near 0 inch H2O in a calibrated time, this DTC sets.
Diagnostic Aids
?€¢
An intermittent condition could be caused by a damaged EVAP vent housing, a temporary blockage at the EVAP canister vent solenoid valve inlet, or a pinched vent hose. A blockage in the vent system will also cause a poor fuel fill problem.


?€¢
An EVAP canister, vent hose, or vent solenoid valve that has restricted flow may cause this DTC to set. Using a purge solenoid command with a scan tool will allow vacuum to be applied to the system instead of pressure. With the engine running, the EVAP canister vent solenoid valve open, and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 5 inches H2O.


?€¢
An EVAP canister filter that is restricted can cause this DTC to set. Refer to Evaporative Emission Canister Replacement .


?€¢
Disconnecting one component at a time while the EVAP system is under flow will help to pinpoint a restriction in the system


Do you have a scan tool that reads data PID'S ?
Your FTP - fuel tank pressure sensor could be at fault !

    Ignition ON and fuel cap removed, verify that the FTP sensor parameter is between 1.3-1.7 volts. ?‡'
    If not within the specified range, go to the FTP sensor section in Circuit/System Testing.

  1. Install the fuel cap.
  2. With the engine running, the EVAP canister vent solenoid valve open, and the EVAP canister purge solenoid valve commanded to 100 percent, the fuel tank vacuum should not increase to more than 12 inches H2O.
?‡'
If the fuel tank vacuum is greater than the specified range, go to the restriction section in Circuit/System Testing.

Computer code 455


Possible causes - Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

When is the code detected? EVAP control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly. Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors P0455 Buick Description This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition. The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.
if tightening the cap or replacing the cap does not help take your car to a shop to have it diagnosed as it requires special tools/equipment to test this and get an accurate results to find what needs replacing.

I have a 2004 buick rendezous the dealer told me I need a cannister vent solenoid cost is $688, however I goolge the part to cost about $50. Will this stop my car from starting after a fuel it with gas?


Shouldn't. The solenoid opens the valve when the computer needs to vent the gas tank to the canister. It will probably keep the check engine light on which will cost you in gas mileage.
I'd get a second opinion on the cost to repair. Any serious garage should be up to the task.

The vehicle wont accept fuel it spills all over and gas gauge is stuck over full??? but runs out of gas,then very very very slowly it accepts very little gas then you can drive again.chevyscott20@yahoo.com


SOUND LIKE YOUR EVAPORATIVE EMISSION CONTROL NOT WORKING.SCAN VECHICLE FOR FOR FAULTY FUEL TANK PRESSURE SENSOR MALFUNCTION.AND THE CANISTER PURGE SOLENOID VALVE OR CANISTER VENT SOLENOID NOT WORKING.CAUSING EXCESSIVE FUEL PRESSURE AND FUMES BUILD UP IN FUEL TANK.CHECK CANISTER IT COULD BE GAS SOAKED NEED REPLACING OR VACUUM LINES GOING TO CANISTER PURGE SOLENOID OR VENT SOLENOID COULD BE BROKEN.PURGE VALVE LOCATED ON THE LEFT SIDE OF THE ENGINE ON A BRACKET AND VENT SOLENOID LOCATED ON A BRACKET NEXT TO FUEL TANK.CHECK BOTH MAKE SURE VACUUM LINES NOT BROKE OR DISCONNECTED.MAKE THE ELECTRICAL CONNECTOR INTACT ALSO.FUEL PRESSURE SENSOR ON TOP OF TANK ON THE FUEL PUMP MODULES.ALL YOU CAN DO IS REMOVE CANISTER SEE IF FULL OF GAS REPLACE IT.AND CHECK FOR BROKE AND DISCONNECTED VACUUM LINES.THE DEALERSHIP HAS TO HOOK UP DIAGNOSTIC EQUIPMENT CHECK IT OUT.BE CHEAPER BECAUSE ALL THEM EVAP PARTS NOT CHEAP THAT WHY LET DEALERSHIP SCAN IT SAVE MONEY IT WILL CUT THE COST.WARNING DONT KEEP DRIVING VECHICLE.GAS VAPORS PRESSURE BUILD UP ON HOT DAY FUELTANK WILL BLOW UP LIKE BALLON.PRESSURE KEEP BUILDING UP.

Error codes P0442 and P0455 in Dodge Dakota 2001


Hello shoretex...Yes sir you can repair this yourself...
p0442 is medium leak detected ...p0456 is small leak....and p0440 is a general evap system failure.. evap codes are a common thing. gas caps are an inexpensive place to start. There are two types of evap hoses on the Dodge... hard plastic and soft rubber.... before you replace parts check the soft rubber first at the evap cans and pump located about a foot in front of the gas tank fill pipe on trucks located next to the transfer case or right behind the trans on the driver side. hard plastic lines will brake or rub through...check spots where lines come in contact with anything. this is a common thing with older trucks...hair line cracks will kick a p0442 code, and a p0445 code...When you find a leak, repair it, and rescan...sometimes there are several leaks, continue with inspection and repairs until you get it all fixed up.... Remember..start at simple and work from there...
i will post the evap. system in more detail to help you troubleshoot the problem.
EVAP System: The Evaporative Emission (EVAP) Control system used on all vehicles is the charcoal canister storage method. This method transfers fuel vapor from the fuel tank to an activated carbon (charcoal) storage device (canister) to hold the vapors when the vehicle is not operating. When the engine is operating, the fuel vapor is purged from the carbon element by intake air flow and consumed in the normal combustion process. The evaporative system includes the following components: *Fuel tank *Evaporative emission canister vent solenoid *Fuel tank pressure sensor *Fuel pipes and hoses *Vapor lines *Fuel cap *Evaporative emission canister *Purge lines *Purge valve solenoid EVAP System Operation: The EVAP purge solenoid valve allows manifold vacuum to purge the canister. The Powertrain Control Module (PCM) supplies a ground to energize the EVAP purge solenoid valve (purge on). The EVAP purge solenoid control is Pulse Width Modulated (PWM) or turned on and off several times a second. The EVAP canister purge PWM duty cycle varies according to the operating conditions determined by the mass air flow, the fuel trim, the engine coolant temperature, and the intake air temperature. For certain EVAP tests, the diagnostic will be disabled if the TP angle increases to above 75% . The evaporative leak detection diagnostic strategy is based on applying vacuum to the EVAP system and monitoring for vacuum decay. The fuel level sensor input to the PCM is used to determine if the fuel level in the tank is correct to run the EVAP diagnostic tests. To ensure sufficient volume in the tank to begin the various diagnostic tests, the fuel level must be between 15% and 85% . The PCM monitors the fuel tank pressure/vacuum level via the fuel tank pressure sensor input. Results of Incorrect Operation: Poor idle, stalling and poor driveability can be caused by the following: *Malfunctioning purge solenoid. *Damaged canister. *Hoses/lines split, cracked and/or not connected properly. Evidence of fuel loss or fuel vapor odor can be caused by the following: *Liquid fuel leaking from the fuel lines *Cracked or damaged canister *Inoperative canister control valve Vacuum hoses that are: *Disconnected *Mis-routed *Kinked *Deteriorated *Damaged The evaporative leak detection diagnostic strategy is based on applying vacuum to the EVAP system and monitoring vacuum decay. The PCM monitors vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid are turned on, allowing engine vacuum to draw a small vacuum on the entire evaporative emission system. After the desired vacuum level has been achieved, the EVAP purge solenoid is turned off, sealing the system. A leak is detected by monitoring for a decrease in vacuum level over a given time period, all other variables remaining constant. A small leak in the system causes DTC P0442 to be set. If the desired vacuum level cannot be achieved in the test described above, a large leak or a faulty EVAP purge solenoid is indicated. This can be caused by the following conditions: *Disconnected or faulty fuel tank pressure sensor. *Missing or faulty fuel cap. *Disconnected, damaged, pinched, or blocked EVAP purge line. *Disconnected or damaged EVAP vent hose. *Disconnected, damaged, pinched, or blocked fuel tank vapor line. *Disconnected or faulty EVAP canister solenoid. *Disconnected or faulty EVAP vent solenoid. *Open ignition feed circuit to the EVAP vent or purge solenoid. *Damaged EVAP canister. Any of the above conditions sets DTC P0440. A restricted or blocked EVAP canister vent path is detected by drawing vacuum into the EVAP system. The PCM turns off the EVAP vent solenoid and the EVAP purge solenoid (EVAP vent solenoid Open, EVAP purge PWM 0% ). The PCM monitors the fuel tank pressure sensor input. With the EVAP vent solenoid open, any vacuum in the system should decrease quickly unless the vent is blocked. A blockage is caused by the following conditions: *Faulty EVAP vent solenoid (stuck closed). *Plugged, kinked, or pinched vent hose. *Shorted EVAP vent solenoid driver circuit. *Plugged evaporative canister.

Good luck shoretex, hope this helps...please take time to rate me a fixya.
