My check engine light and VSC Trac lights came on at the same time and stay on. What is the possible problem here?

Answers from the Automotive Experts

Brandy Schaffels, Editor at AskPatty.com, Inc. You can have the diagnostic codes scanned at your dealership, or a local auto parts store to get more information about the problem. Typical causes for these can include anything from a loose gas cap to evaporative emission system, evaporative canister or hose not connected, vacuum leak at engine, defective solenoid, or a vacuum leak in the engine. For additional assistance, please find an AskPatty Certified Repair Shop at http://www.askpatty.com/search/?type=all&m=30&q=&keyword= and they can help you diagnose and repair the problem.
