EVAP Leak Detection

Basic Description
The evaporative emissions system or EVAP system, captures vapors from the gas tank and stores them in a charcoal canister. When the engine is started, the vapors are moved from the canister to the intake manifold to be burned. Fuel vapors released into the air contribute to smog. The purpose of the EVAP system is to capture these fuel vapors that would otherwise escape and enter the atmosphere. The vent valve, normally located near the charcoal canister, allows fresh air in the EVAP system when the purge valve opens.


At Calibey's Oakhurst Auto, we subscribe to a professional auto repair information system as well as the most thorough database in the industry of proven experience-based repairs from the best technical experts in the auto industry. Our engine diagnostic services help us to provide you with an accurate diagnosis of your vehicle's engine problem and a repair that is done correctly the first time.​

FREE VEHICLE DIAGNOSTIC CODE SCAN​

WHAT DO I GET FOR MY DIAGNOSTIC FEE?

Our Free Code Scan service is an informational service that we perform for free. We will connect to your vehicle and retrieve the codes that are triggering your light to illuminate. We will also provide you with an easy to read print out. Once we have a better understanding of what is triggering your light to illuminate, our trained customer service associates will recommend the appropriate service. This service should be performed when you have a check engine light illuminated and are looking to receive preliminary information before committing to further work.

When your Check Engine light comes on, a trouble code will be stored in one or more of your vehicle's computers. There are certain conditions (usually 4-5 specific criteria) that have to be met for a trouble code to set, and it is vitally important that the technician who is diagnosing your car checks all of them before he/she makes a repair decision.


The diagnostic trouble code (DTC) is effectively the “tip of the iceberg”. The trouble code takes you to “an area” for further testing to properly determine where the real fault is. The diagnostic fee allows us the time to thoroughly test and accurately determine the real cause of the warning light using the professional test equipment we have invested in.

Leak testing​
Parts of the EVAP system can fail and cause leaks. A special process has been developed to find these leaks. Leaks in the EVAP system can be difficult to find since fuel vapor and air are invisible to the eye. When a trouble code is read dealing with an EVAP problem, leaks in the system should be one of the first things to check. A machine that produces smoke is connected to the EVAP test port. All valves in the EVAP system should be sealed by use of a scanner. As smoke circulates through the EVAP system, it will leak from the hole in the system. In this way, the leak can be detected and then repaired.
