There are 11 EVAP codes so can you post again with the code/s that keep coming up
post every code that has come up to suggest that it is the EVAP system problem

SOURCE: insufficient egr flow, already replaced egr valve

I too replaced the egr valve and was discouraged that the check engine light came back on with the same "insufficient flow" code. I took it to my mechanic to put it on the monster diagnostic machine. It said "check all vacuum line, and or map sensor". After looking real close we found a melted vacuum tube, and a cracked vacuum angle connector. Replaced both vacuum pieces, reset the codes, and good to go. If that fails than the next thing is the map sensor, that tells the EGR valve what to do.

SOURCE: 2008 envoy code reader showing high purge flow on

common problem with those mods ,is evap purge valve would get stuck open,then after shutdown vapors from fuel supply sys would flood engine with excessive fuel vapor ,so when you go to start vehicle it would act like a flooded engine and take longer cranking before it starts,try holding gas pedal to floor after a 15 min shutdown and see if starts faster,i believe that purge valve is along the d/s of the engine block.

SOURCE: 2006 Hyundai elantra purge problem replaced the purge valve and still days for a code incorrect flow and then a code for a evaporated small leak / no flow I need help

This is generally caused by a leak in the hose somewhere. This hose is long in length plastic and has several places it could be leaking from. You'll have to take it to a shop that is equipped with a leak tester that uses smoke. They will fill the hose with smoke and easily find the leak. There really is no easy way to find it other than that. Hope that helps you.

P0496 code


Hi there:
DTC P0496 - EVAP (evaporative emission) Flow During A Non-Purge Condition


The P0496 DTC code is a generic code which applies to all vehicle makes. A quick search on the 'net shows that this code seems to be more common with GM (Chevy, Pontiac, etc.) vehicles. In Acura, Honda, Hyundai, Kia, and Mazda vehicles, this code is described "EVAP system high purge flow" which is the same thing.


This DTC checks for undesired intake vacuum flow to the EVAP system. The control module seals the EVAP system by commanding the EVAP canister purge solenoid valve OFF and the EVAP canister vent solenoid valve ON. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system

If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this code is set and the MIL (malfunction indicator lamp) is illuminated.



Symptoms of a P0496 DTC will include MIL illumination, and most likely no other noticeable symptoms. Some may experience a hard start / crank condition. In some cases the engine may run rich which may not detected, but can cause damage long-term (think: catalytic converter damage).

Potential causes of a P0496 EVAP code include:

  • Faulty purge or vent solenod/valve
  • Plugged EVAP canister
  • Failed EVAP / fuel pressure sensor
  • Poor electrical connection
  • Short electrical circuit condition
  • (Hyundai, Isuzu)
  • Faulty canister purge valve
  • Blocked vapor canister
  • Faulty vent solenoid
  • Leaking EVAP system hose (Hyundai)
  • Faulty purge flow sensor (Kia, Mazda)

Possible Solutions

The most common fix for this DTC is to replace the purge solenoid valve. However, be sure to do a proper diagnosis before replacing parts!

Ideally you would use an advanced scan tool, with the ignition on and engine off, you seal the EVAP system using the Seal/Purge function. Then, watch the fuel tank pressure sensor reading when you turn the purge off. If the pressure value is higher than the normal range set by the manufacturer, replace the EVAP canister purge solenoid valve. Refer to a model-specific repair guide for the proper specification.


If you don't have access to the scan tool, you could always disconnect the vacuum line at the purge valve going back to the charcoal canister. Unplug the electrical connector on the purge valve, start the engine, then put your finger on the valve where you disconnected the line. If you can feel vacuum there, the purge solenoid valve is faulty and needs to be replaced. Alternately, you could simply remove the purge solenoid valve and blow into it. It is normally closed, so if air goes through then you need to replace it.


If the purge valve checks out good, either the problem with the valve is intermittent or there is a problem with the fuel tank pressure sensor. To test the fuel tank pressure sensor you will need to have a high end scan tool to monitor the tank pressure with the gas cap removed. If the sensor shows vacuum with the gas cap removed, there is a problem with the fuel tank pressure sensor.


Here is a picture of one purge solenoid valve. Yours may look similar or different, consult a factory service guide or your local vehicle dealership for more details.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Car won't start after putting gas in it kia 2003


I have seen this problem several times. The EVAP Purge Solenoid in the engine compartment is sticking open. When you refuel your vehicle, the open solenoid is allowing fumes from the fuel tank to flood the intake manifold with fumes. This is what is keeping your engine from starting...too much fuel and very little air. Most of the time your check engine light will also be coming on while you are driving your vehicle and the code that sets will say "P0441 Evaporative Emission System Incorrect Purge Flow" or there will be some other manufacturer-specific code or code description that will read something like "Purge Detected During Non-Purge" or "Purge Control Valve Stuck Open". However, I have also seen this happen without setting any codes at all (also see below). In each case that I have encountered, replacing the purge valve fixed the problem.

Also make sure your engine is turned off and the ignition switch is in the OFF or LOCK position when refueling. I have also seen this caused when somebody turns the engine off, then turns the ignition back to the ON position so passengers can "listen to the stereo" during the refueling process. This can cause the computer to open the purge valve during refueling. When it happens this way, there will be no fault codes stored and no repairs need to be made to the vehicle.

Codes P0401 and P0441 on a 1996 98 Olds


P0401--- the egr valve has insufficient air flow. Needs to be taken off and cleaned, if not replaced. The port holes might be clogged up, or the valve itself might be bad.
P0441---- The evaporative emission control purge valve has low air flow, probably do to the egr valve.
If you take off the egr valve, you will need to replace the gasket, or it won't seal right when it's put back on.

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:)
