If you have EVAP leak, or a hidden exhaust leak, this tool will save your day!


Check engine lights are sometimes accompanied by noises, smells, and vibrations that can help diagnose the underlying issue. But sometimes, that annoying little light comes on with no other indication of what’s up. That’s sometimes the case with leaks in the EVAP system.
What is an EVAP leak, you might be asking? An EVAP leak is a fault in the evaporative emission control system (EVAP). The EVAP’s function is to keep gasoline fumes in the fuel tank from reaching the atmosphere. This keeps air pollution down and keeps the smell of fuel from reaching the inside of your vehicle.

Fuel vapors are emitted from vehicles any time there is gasoline in the tank. So if you have a leak, even if you are not driving the vehicle, those vapors are polluting the air 24 hours a day. Uncontrolled emissions like this account for about 20 percent of the pollution produced by vehicles.

Check Engine Light Illuminates

There are many reasons why the check engine light comes on while driving, and an EVAP leak is just one of them. A slight fuel odor may also be noticed, but not in all vehicles. If you have just filled the tank and the check engine light does come on, check for a loose gas cap.
The most common cause of an EVAP leak warning is an air cap that is not properly closed. If the lid is not fully tightened or fully closed, the check engine light may come on. Before taking your vehicle to a repair shop, check your gas cap to ensure it is properly placed.

Leak in the Fuel System

More serious problems, such as fuel system leaks, may exist if the fuel tank cap is properly closed.

How Much Does it Cost to Repair an EVAP Leak?

The EVAP leak repair cost depends on what type of code you face. Replacing a broken gas cap only costs you about $10, while the price to replace an EVAP canister is much more. In fact, these canisters can often cost $200 or more just for the parts.
