Usualy about 5 seconds will do it. But I usualy leave it off for about 30 just for the heck of it. That should clear it, but it will probably come right back on. Dont rely on what autozone says the code means. If you look at alldata there are usualy 3 to 4 pages of troubleshooting steps to go through after you get the code to determine what is causing it. Some easy ones are simple, but most of them aernt. For instance an O2 code can be cause by a faulty EGR valve bleeding exaust in, and causing the engine to be lean. Or a pinole exaust leak right before the sensor can trip a bad sensor code too.
Check and see what the code is and let us know.

Its not always about who gets to the finish line first, its who looks good when they get there. 'Course it doesnt hurt to have both.
