Evaporative Emissions Control

Last Updated: Apr 05, 2015

The Evaporative Emissions System (EVAP) purpose is to prevent fuel vapors from escaping into the atmosphere and direct them into the engine to be burned – kind of an on-board recycling program.

The EVAP system is a complicated network of hoses, valves, filters and such. Issues with the EVAP system are in the Top 5 reasons for a Check Engine Light to be illuminated. Your friendly and knowledgeable Mountain Auto Care advisor can pull the trouble codes and begin a diagnostic procedure to isolate the fault.

With the proper equipment, your can test the valves in order to trace a blockage. A low pressure smoke test can be performed to find any leaks. The repairs are then made to get the EVAP system working again and to reset the Check Engine Light.

While EVAP s don't generally lead to vehicle damage, the fact that they trigger the Check Engine Light can mask other more serious problems for Durango residents if left unaddressed. After all, there are hundreds of conditions that can trigger a Check Engine Light – but there is only one light. So if the light is on because of an EVAP issue you haven't fixed and another arises, you won't be alerted to the new condition because the light is already on.

Of course, if you live in a jurisdiction in Colorado that requires emissions testing to register your vehicle, you won't pass the test until you make the repairs. An EVAP trouble code could be caused by something as simple as a loose or worn gas cap or a leak in a hose to problems with a purge valve of even a rusty fuel filler pipe.

When your Check Engine Light comes on, bring your vehicle into Mountain Auto Care in Durango and let us check it out. Your Mountain Auto Care service advisor will be able to diagnose the issue and work out a plan to address any problems that are uncovered. There's peace of mind for Southwest Colorado drivers that comes from knowing what is wrong and taking care of it.
