Look around the inside lower part of your passenger fender, under hood. They used to look like an old tomato juice can, but not sure on yours, but will have vacuum lines running to it, and at least one of those lines will run up to a switch on the side of fender area, which is usually your purge solenoid.

DTC P0446 Evaporative Emission (EVAP) Vent System Performance

The vehicle control module (VCM) monitors the performance of the evaporative emission (EVAP) system by applying a predetermined level of vacuum to the EVAP system and monitors the vacuum decay rate. The VCM sets this diagnostic trouble code (DTC) if the vacuum decay rate is more than a predetermined value. The VCM monitors the amount of vacuum and the amount of pressure in the EVAP system by monitoring the fuel tank pressure sensor. For this DTC, the VCM turns ON both the EVAP purge valve and the EVAP vent valve when the Conditions for Running the DTC are met. This applies an engine vacuum to a closed EVAP system. The VCM turns OFF both the EVAP purge valve and the EVAP vent valve when the system reaches a correct amount of vacuum. The EVAP system should quickly RELEASE the vacuum in the EVAP system with the EVAP purge valve OFF and the EVAP vent valve OFF (open). This test indicates a blocked or restricted EVAP vent path if the EVAP system fails to release the vacuum quickly enough.

Where is purge sensor located


There is no such thing , What code do you have if any ? There is a purge solenoid for the EVAP system ! evaporative emission system. An there is a vent solenoid , a fuel tank pressure (FTP) sensor.
The evaporative emission (EVAP) control system limits fuel vapors from escaping into the atmosphere. Fuel tank vapors are allowed to move from the fuel tank, due to pressure in the tank, through the vapor pipe, into the EVAP canister. Carbon in the canister absorbs and stores the fuel vapors. Excess pressure is vented through the vent line and EVAP vent valve to atmosphere. The EVAP canister stores the fuel vapors until the engine is able to use them. At an appropriate time, the control module will command the EVAP purge valve ON, open, allowing engine vacuum to be applied to the EVAP canister. With the EVAP vent valve OFF, open, fresh air will be drawn through the valve and vent line to the EVAP canister. Fresh air is drawn through the canister, pulling fuel vapors from the carbon. The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge valve into the intake manifold to be consumed during normal combustion. The control module uses several tests to determine if the EVAP system is leaking.

What is evaporation control system malfuction mean? The code is P0440


Hi, the computer has sensed through the fuel tank pressure sensor that the vapor cannister is not evacuating properly. I have pasted details on the EVAP system below. Check the purge valve on top of the engine as shown below (#1 in picture). Make sure the electrical connector is on the valve, that the wires are not damaged, and check the hose for kinks. If all looks good, I recommend you replace the valve. A new valve is $23 at autozone. Please let me know if you have more questions and thanks for using FixYa.

Description & Operation
EVAP Canister
The canister is filled with carbon pellets used to absorb and store fuel vapors. Fuel vapor is stored in the canister until the control module determines that the vapor can be consumed in the normal combustion process.
EVAP Control System
The evaporative emission (EVAP) control system limits fuel vapors from escaping into the atmosphere. Fuel tank vapors are allowed to move from the fuel tank, due to pressure in the tank, through the vapor pipe, into the EVAP canister. Carbon in the canister absorbs and stores the fuel vapors. Excess pressure is vented through the vent line and EVAP vent solenoid to atmosphere.
The EVAP canister stores the fuel vapors until the engine is able to use them. At an appropriate time, the control module will command the EVAP purge solenoid ON, open, allowing engine vacuum to be applied to the EVAP canister. With the EVAP vent solenoid OFF, open, fresh air will be drawn through the solenoid and vent line to the EVAP canister. Fresh air is drawn through the canister, pulling fuel vapors from the carbon.
The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge solenoid into the intake manifold to be consumed during normal combustion. The control module uses several tests to determine if the EVAP system is leaking.
The EVAP system consists of the following components:
EVAP Purge Solenoid
The EVAP purge solenoid controls the flow of vapors from the EVAP system to the intake manifold. This normally closed solenoid is pulse width modulated (PWM) by the control module to precisely control the flow of fuel vapor to the engine. The solenoid will also be opened during some portions of the EVAP testing, allowing engine vacuum to enter the EVAP system.
EVAP Service Port
The EVAP service port is located in the EVAP purge pipe between the EVAP purge solenoid and the EVAP canister. The service port is identified by a green colored cap.
EVAP Vent Solenoid
The EVAP vent solenoid controls fresh airflow into the EVAP canister. The solenoid is normally open. The control module will command the solenoid closed during some EVAP tests, allowing the system to be tested for leaks.
Fuel Tank Pressure Sensor
The FTP sensor measures the difference between the pressure or vacuum in the fuel tank and outside air pressure. The control module provides a 5-volt reference and a ground to the FTP sensor. The FTP sensor provides a signal voltage back to the control module that can vary between 0.1-4.9 volts. As FTP increases, FTP sensor voltage decreases, high pressure = low voltage. As FTP decreases, FTP voltage increases, low pressure or vacuum = high voltage.

Check engine light comes on and then it will go off, when on we went to auto zone, the troubleshooting code was PO445, they said it was purge or vent solenoid. what does this part do.


the purge valve canister collects fuel vapor during the time you are driving and releases them back to the intake manifold to burn with air and fuel as you are driving. during the time the car is setting still over night any fuel vapor will go back to purge canister to start again when you drive. location of canister is in front of fuel tank on driverside. hope this will help you!!!!

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.
