I know the durametric software can clear fault codes, but can it be cleared so my car can pass smog? I'm currently fiddling with a 0430 code and I think the car should pass because the prior owner successfully smogged it about 4 months ago. It's just the annoying light that is preventing me from smogging the car.
Is the 0430 the only alarm you have? How does the seal on your gas cap look?
