Occasionally, the Check Engine Light is illuminated due to failures in the evaporative emission (EVAP) system. Our technicians tell us that proper diagnoses is generally required to confirm the exact fault causing the warning light to come on.

This started happening after a tune-up at a local Meineke. They basically gave up on finding the leak. I've had to play some games to pass inspection (reset ecu, complete a drive cycle, get it inspected prior to light coming back on).
