Take your pick:

P0440 Evaporative Emission Control System Malfunction
P0441 Evaporative Emission Control System Incorrect Purge Flow
P0442 Evaporative Emission Control System Leak Detected (small leak)
P0443 Evaporative Emission Control System Purge Control Valve Circuit Malfunction
P0444 Evaporative Emission Control System Purge Control Valve Circuit Open
P0445 Evaporative Emission Control System Purge Control Valve Circuit Shorted
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
P0447 Evaporative Emission Control System Vent Control Circuit Open
P0448 Evaporative Emission Control System Vent Control Circuit Shorted
P0449 Evaporative Emission Control System Vent Valve/Solenoid Circuit Malfunction
P0450 Evaporative Emission Control System Pressure Sensor Malfunction
P0451 Evaporative Emission Control System Pressure Sensor Range/Performance
P0452 Evaporative Emission Control System Pressure Sensor Low Input
P0453 Evaporative Emission Control System Pressure Sensor High Input
P0454 Evaporative Emission Control System Pressure Sensor Intermittent
P0455 Evaporative Emission Control System Leak Detected (gross leak)


It could be a gas cap leak, or most likely not. The generic p0440 means that there is a leak in the evap system, somewhere. Much sucess has been found to point to a 90 degree elbow near the fuel filter, in the passenger side rear wheel well.
Autozone will no longer clear codes. If they did, you could probably get tested immediately after the clear and it will not show up on the scanners for a day or two. The real problem is finding the leak, fixing it is easy.

Time to get on the web and get a scanner. You will save a lot of time if you have your own. Do a search on DTC and you will find a list of all codes.
