Depending on the code reader, there may not be any showing up? I have the extended (Ford and GM vehicles) of Auto Enginuity and before I got the extened versions nothing showed up. Also it only showed about 150 sensors and now it shows about 17,500 check points including chassis, brakes, steering and transmission. If you were in the San Diego area I could plug it in and see what is really going on.
