Just bought the car listed above, engine light is on. When OBD is read it says (P0433 Evaporative Emission System Purge Control Valve Circuit) I have changed fuses, bought a new gas cap, and replaced the purge control valve. I can hear the purge valve ticking as it should, I have erased the code and it comes back the next time the car is turned off and restarted.
Any suggestions?

Hello,

Keep in mind that sometimes the issue is due to the electrical circuit for the valves.
