Scotty Kilmer, mechanic for the last 46 years, shows how you may be able to get your car to pass the emissions inspection test if it failed because of the check engine light being on with code P0420 stored. Simply erasing the code and driving the car on the highway for half an hour often will work. And, If you like my car help, be sure to watch my live car talk show every Saturday morning at 10 AM CST on YouTube. I answer your car questions LIVE there.
