I had it on my car, You have to replace the vent canistor control valve. Your car will run better once its fixed, gas milage may go up.

This is a "jackpot" DTC. It points to so many things you don't know what to check. It is often combined with another DTC which is more specific and therefore more helpful.

To be honest i dont know, because I get a discount for working at a stealer ship. Normal price should be under 80-90 $ . Its not hard to do , I had my mechanic do it in 1/2 hours and that includes taking rusted bolts off. It shouldnt take more then 1 or 2 hours depending on your skills, and if you have a lift for your car, or jacks or anything else.
