so im on the hwy on cruise control and ses comes on.. went directly to nissan for a scan, it was 5pm n tech were leaving so they rushed to get me code. They said it was something to do with the front of the exhaust, like a air sensor or filter or something, honestly i forget. he said it was osmehting similar to a o2 sensor, but located @ the front of the exhaust area. He said nothing bad, but will effect my mpg. anyone know what hes talking about? im going to call tmrw, he couldnt get the info for me cuz he wanted 2 go home lol. thanks

bingo! thats it! i remeber hearing that! i have stock exhaust... but shop BROKE my o2 off the bung when installing my aftermarket exhaust. and refused to replace so i had it welded on the stock exhaust since im going FI in a month or so. can this be cuased from that? ( this happened like 2 months ago) is it bad?

well the light just went on.. does that mean the sensor just went bad? or its been bad and the computer just picked it up? dropping it off tmrw after work. you think any damage has been done?
