Hey I retrieved this error today, it says No activity Detected (Bank 1 - Sensor 1). What does this mean and how do I get rid of the CEL...oh yeah I have the AEM short ram intake. Thanks

I think it means the o2 sensor went bad, probably the one on your downpipe. I am not 100 percent sure on that though.

Thanks for the reply, I don't know if it is the sensor right away because my mileage has not been affected and not only that but the stupid light has been off all day and it usually comes on when I get the car nice and hot after driving for a while, but today I was on the highway all day and I was going at least 80 the whole time and it has been hot around here, so I am really stumped on what to do. The service manual didn't do jack shit to help either, anymore help is greatly appreaciated.
