i unplugged the sensor on the air box taking the box off and when i put it back together forgot to hook it back up then i started it up , then i remembered it rehooked up it was off no more than 2min and the check engine light is on i disconnected the batteries for a few min. still wont go off how can i cut it off, 06 3500 drw 5.9 thanks

 

i will go out after a few start/stop cycles. full warm up, cool down. several times will take care of it. no worries.

 

Go to Autozone ,or the parts store you have, & use there scan tool & erase it(after you read it to make sure that's what it is).
