Getting a code PO440 which is Evaporative Emission
Control malfunction. No idea how or what to fix.
Car runs fine. No problems just the engine light is on and the code reading above. HELP?

There is a leak in the EVAP system. It could be a bad gas cap to other leaks. What I suggest is first determine if it is a leak. If so, have the system fogged to identify where the leak is coming from.
