The fuse was the canister vent valve, exhaust oxygen sensor. The car wont start. When i changed the fuse it started, but blew again. Also the remote key does not lock or unlock the doors. Does anyone know why?
2 days ago, my chk eng light came on. Scan tool showed code p0440, i found a fuse that was blown.?
Sounds like a wiring issue. Anytime you replace a fuse and it blows again, that means it is not properly grounded. You'll have to find the ground that the fuse is linked too and reground it....I know, easier said than done. Replace your gas cap just to be sure. Have you noticed a stronger exhaust smell lately? Could be your emissions and need to get that fixed quick. Bad emissions kills your fuel mileage. As for the key, make sure that tiny little battery is good inside the clicker. Autozone has testers for these things so try that. Does the manual locks work? If they do then it's probably your clicker.

P0440 Evaporative Emission Control System Malfunction
The fuse blowing is causing that code, but you will need to find and repair the short that is causing the fuse to blow.
Chances are the battery in your remote is dead. Replace the battery and reprogram the remote.
you don't have an open like the other answerer suggests. You have a short to ground. (the wire feeding power to the circuit in question has been grounded before the load, causing the circuit protection to trip, in this case a fuse)
Your short may be in the wires feeding the vent valve or the vent valve itself. Unplug the vent valve, then replace the fuse. If it blows again, take a close look at the wires that go from the fuse block to the valve connector. One of them may be exposed and shorting to either the chassis or another wire in the harness.
If it does not blow the fuse, see what happens if you plug in the vent valve... if it blows, you know the valve itself is faulty. There are diagnostic ways to tell if it's bad without going through fuses, but honestly, this is the easiest way to do it.
If this vehicle has been in a recent accident, at times wire looms get crushed in the damage, and wires get pinched together. This can cause all sorts of interesting symptoms with seemingly no connection. I'd check in the area of the impact, if that's the case.
