My Diagnostic book states ''Evaporate Emission Control'' Has a small leak in it. This is the charcoal canister under the hood. It has two valves on it. A purge control valve , and a canister close valve. One of the two is leaking. All it does is help to get better Emissions out the tail pipe. If you do not have to do a Emission test don`t worry about it.If you do have to have it tested you should bring it in to a dealer. Most other places won`t know how to fix this one. Good Luck!

The evaporative system checks for leaks in the fuel tank and lines and if it detects a small leak, it sets this code. The cause can be from a leaking gas cap, canister shut-off valve, fuel tank, fuel lines, or a charcoal canister. Take it to a shop that uses a smoke machine to detect small leaks in these types of systems.

Good Luck!
