Both codes mean: Evaporative Emmission Control System Leak Detected (very small leak)


This may be a very tough issue to diagnose or it may be a simple problem like a loose gas cap.

Check the gas cap, and visually check for any loose hoses under the hood and under the car.

If something is found, repair it, then clear the codes.

Let me know.
