Question:

Check Engine light--AutoZone got code: P0446. Has anyone experienced this? Does it require immediate attention?

This code is coming from my wife‘s 1998 Toyota Camry (3.0L V6).The print-out that I got from Auto Zone says this:Evaporative emission control system vent control circuit faultProbable causes:1. Open or short circuit condition2. Poor electrical connection3. Faulty CCV vent control solenoidIf anyone has had any similar codes from their car, please let me know if it needs to be checked out right away or if it can wait a week or two.I know, the sooner the better.but realistically, we can‘t get it checked out right away.Any help would be greatly appreciated. Thanks!!

Answer:

Sure open is a possibility
This is not a serious problem and you can safely operate the car with the check engine light lit. The Evaporative emmission control system is designed to prevent the gas in your gas tank from venting fumes into the atmosphere since gasoline evaporates easily. When the system does not work properly, the check engine light must come on according to government polution regulation law. However, your car is just fine. Make sure the gas cap is on tightly (clicks when you turn it tight) and you are good to go.
No biggie. It will fail smog test, but won't hurt anything. It should be a simple fix.Parts and labor +/- $100. A check engine light indicates that there is a sensor that is reading a condition that is out of range. Simply resetting the light does not solve the initial cause of the problem. Replacing a number of parts trying to troubleshoot the problem in the hopes of getting the light to stay off is a tremendous waste of time and money. The simplest, and most economical way to alleviate your issue, is to have an engine diagnostic done by a reputable shop to determine what caused the computer to signal you to begin with. Just reading the computer codes may not find the cause.
