Failed Emissions

How many miles does it take to clear the codes from memory? The clip on my mass air flow sensor was broken and it came off. Subsequently, I fixed the problem. However, I thought I drove enough to clear the codes, but the emissions testing facility still found it.

You can plug an OBD-II scanner and simply scan/clear the "Codes".

Or take your truck to Autozone & ask to borrow theirs... Scan & clear

What's said above but you'll still have to put miles on to set the monitors. Clear the codes with a scanner or by disconnecting the battery for awhile. Then put ~50 miles on and should be good. Can probably get away with less but do you really want to go and waste time failing again?
