Re: Fuel tank pressure sensor
Never messed with fuel tank pressure sensor, but I've dealt with similar technologies elsewhere. Usually a 0 psi signal still sends some sort of a signal, so if the controlling device doesn't see any signal at all, it'll still throw a code. Can't see why it would be different on a car.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
