you would need a scan tool to reset it, if it is the gas cap and you fixed the problem with it then the light will go out after 100 miles of driving with a couple of cold starts. if it doesnt go out after a few days of driving then that wasnt the problem.

The converter should last 10 or 15 years if you don't have issues that damage it. Get thoses codes checked out and repaired. If you have antifreeze entering the exhaust,a leaking fuel injector,bad o2 sensor etc,that could ruin the converter,if you drive it that way for a year or more. The converter may be installed wrong or an exhaust joint is leaking in air and setting a code. o2 sensor loose and other issues. Have to start somewhere and walk it down untill you find the problem.

SOURCE: service engine light-evap code,any common places to look???

In order to find that requires what is called a smoke machine. The evap is a very low pressure system, and a leak is almost impossible to detect. The smoke machine puts a low pressure stream of smoke into the system through a port in the engine compartment and then you follow the lines back to the tank, generally with a light to see the smoke coming out.

Hope this helps

My check engine light came on code P0446; dashboard says "check gas cap" i took it off retightened it and check engine light still on. I noticed that the metal flap for the gas nozzle is...


The metal flap should not trigger the sensor. Once you tighten the gas cap you should clear the code and see if it comes back. Otherwise it will take a while to go away.
If it does come back even though the gas cap is tight it could be the rubber seal around the gas cap replacing that can sometimes fix this issue also.

Why would you replace a gas cap?
You were told, two EVAP Codes ,and what they were.
Have the vehicle smoke tested and repaired. You have two different size leaks,in that system.

2007 Chevy Colbalt 2.2 engine P0446 Code is on. what does it mean and how much does it cost to fix


Code P0446 is related to your vehicles evaporative emissions system. Often this is caused by your gas cap not being properly tightened.

Before running out and spending money on this issue be sure the gas cap is in good condition and make sure it's tight. (At least 2 or 3 turns after it begins to click)

Drive the car for a few days. If the check engine light doesn't turn off you will need to go to a repair shop who can scan and troubleshoot the problem.

Good luck.

Check engine code "P0446 Evap Control System Vent Control Circ"


Unfortunately, this code has nothing to do with the gas cap....
A code P0446 could mean one or more of the following has happened:
  • Faulty vent valve
  • Open, short or excessive resistance on Vent valve control circuit
  • Blockage of vent valve
  • Bad PCM
Here are some things you could try to fix it:
  • Replace Vent valve
  • Repair open, short, or resistance problem in control circuit
  • Repair open, or short, or resistance problem in power circuit
  • Replace PCM

2002 Buick Century, when the tank is 1/4 full,


P0446 Evaporative Emission Control System Vent Control Circuit Malfunction

The evaporative emission control system checks to make sure there are no leaks in the lines that run from the gas tank to the charcoal canister and up to the engine. It also checks to make sure the gas cap is sealing correctly.
It may just be that the cap was not on tight and the code was tripped.

A dusty environment can also clog the vent line and cause this code.
Have the code cleared and see if it comes back. Some auto parts stores like Auto Zone can read and clear the codes for you.
Hope this helps.
