SOURCE: Evaporative emission system - small leak/no BB flow condition

Although I recommend you buy a Haynes service manual for your Dodge, I think you will find the canister attached to the firewall or one of the fender wells. Most of them look a lot like an overgrown spam can and it will have two connections on it.

Check all of your EVAP lines and the charcoal canister. Also check the lines and overflow line from the gas cap to the gas tank.

SOURCE: code po449 States "Evaporative emission control

Check engine P codes. GM uses an EVAP solenoid that is located under most vehicles near the gas tank and connects to the charcoal filter can. Codes can be set and will drive you crazy trying to figure out if you have a bad gas cap, broke lines---this is where they try to get you to do a smoke test, or you just think the vehicle is no good.

Relax, it is usually an easy fix and one GM has known about for years but continues to make easy money off people who cannot do basic maintenance. Now one code that comes up is usually P0449, along with maybe a warning to check the gas cap to see if it is on tight. Chevrolet will gladly read this code out for you for around $98.00 and then fix it for another around $100.00 which includes the EVAP part which if you buy at their parts dept. will cost you $32.00 and my dealership parts man told me they sell one a day! It is easy money for them and obviously a defective part they keep using for the last 10 or 15 years but hey, its money in their pocket. Here is how to fix it with ONE single common screwdriver!

Get under the vehicle after putting on the parking brake and if you a little hefty, then removing the spare tire on the some vehicles will give you lots more room. The EVAP solenoid is easy to spot near the gas tank and it has one electric connector which disconnects by releasing the plastic clip and pulling the connector out. It also has ONE air line connected which goes to the charcoal cannister which also can be removed with the one screwdriver. The whole EVAP solenoid and air can can be removed with the screwdriver which makes it easier to unpolug the electric and air line. Get a replacement from the dealer as they certainly are familar with this part as they sell LOTS of them. Then just go under and plug the new one in and the problem is solved. Now if you do not have a tool to reset the codes, try the local parts places as most of them will do a reset for you. If you do not have someone to do it, it can be done simply be removing the RED, positive lead off the battery and wait a minute and then plug it back in. The codes are reset but of course now you have to reset the radio and clock stuff.

Hope helps (remember to rate this answer).

Replaced a evaporator emission canister, and tried to reset so that the light would go off and it would for a little while and come back on need help for the correct code

Correct code ??
The code probably said there was a problem with the function of the evap system, but not that a part needed to be replaced.
Since the actual problem has not been fixed, the warning light continues to come on.
If the dealer replaced the canister you should have them refund your money for the part and try again.

Error code 340 & 457

  • P0340 - Camshaft position sensor circuit malfunction.
  • P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)

    There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

Obd computer won't reset

you can force the engine light to come on with ready or not software (type it in on google) i have this gear. your ecu has to reconise all emmissions sensors data on a 3times in a row before it will complete a full diagnostics cycle.
the ready or not scanner and software will atomatically do everything for you and tell you when everything is ready (so much easier than messing about guessing all the time).
you can also program scanner to your state regulations aswell.think it's about $50 now

hope this helps.

What is the canister?

"Canister" usually refers to the charcoal canister. It's part of an emissions system called the evap system. It's a canister that contains a refined form of charcoal that absorbs evaporated gasoline from the fuel tank, and stores it until the computer opens a valve and it is burned by the engine.

2005 LeSabre check engine light on due to evaporative emissions

Finding a leak in these emission systems is almost impossible.
All it takes is a pin hole in a hose to screw up the whole system.
The best way to find the leak is to take and have a smoke test done on it. Smoke is injected into the system and where ever the leak is , the smoke will leak out of it. It's faster and more reliable then replacing hoses and other things you don't need. Call dealers, or repair shops to see who does smoke tests.

2002 Nissan Sentra Check engine light diagnostics

There is a leak somewhere in the evaporative emission control system. The best way to test that is have a smoke test done on it to find out where the leak is. You'll have to call around to see if any repair shops have a smoke machine, or call a dealer.
