Question about 2001 Pontiac Grand Am SE
The canister vent valve and the oxygen sensors get their power from this fuse(along with some other things) wich means you could have a bad component or a wiring problem anywhere between them and that blown fuse. You can try to unplug each component and try it again. just a suggestion - try the oxygen sensors first as they have a heater circuit inside them wich can short out. The pink and black wire going to the vent valve should be 12 volts with a good fuse in that circuit. Get a circuit breaker from radio shack or napa to go into that blowing fuse so you don't keep having to throw all your fuses out after you blow them. The po440 means you have a small leak in the evap system but you need to repair the blowing fuse first wich could also have something to do with the vent valve- they go bad very often.- good luck
