In a classic Sean moment, I was on my way to get the cruiser inspected when I looked down and saw the CEL. Thanks to this board (as usual) I headed over to Autozone (note to self: it's Autozone not Autobarn where some guy whispered to me that it is Autozone that will read the code) - sure enough it was the P0401 code as has been talked about so much here. He shut off the CEL and the truck passed inspection. Notably, NOX was not tested for - maybe a NY thing. The question is: could this be a fluke, or am I to expect the CEL back shortly?
