Ok so I have an 04 GTP and have had my tire pressure light come on before. Found the low tire and repaired accordingly, no problem. I have worked in a chevy garage before and have delt with the sensors before (band and valvestem type). While replacing two tires I discovered to my confusion, no tire pressure sensors!!!!! How the hell can this be? How can the car know when the tire pressure is low if there aren't sensors? I am very confused by this. I guess I should have known something was screwy when I put my winter wheels (monte wheels) on, the system didn't give me any trouble and I didn't have to do any reprogramming to reconize the different wheels. And the light came on when I had a low tire too!! I've been baffled by this and Hopefully somebody can shed some light on the situation for me. Thanks!!!
