Hi there,

Without knowing your specific engine size or model, all I can do is give you the bases of the code. The code definition is

P0443- Evaporative Emission Control System Purge Control Valve Circuit

Basically this is the part that controls how the vapors in the charcoal canister are pulled out and into the engine to burn when the car is running. This is typically mounted under the hood and opens at specific conditions when commanded by the ecm.
