I wouldn't think so at this point. I would run a direct power lead to the fan to see if it works first. Or first look at the wires to see if any visually are bad, and check the plugin, take it apart and see if there is corrosion on the terminals. Test for power at the plugin.

I already checked wires checked plugs for corrosion and everything. Looks good and also wen i turn car on the fan blows hard and makes a loud buzzing sound

Sounds like the fan clutch is locked up and spinning faster than it should. That will set this trouble code as well as a fan that's spinning too slowly. Replace the fan clutch and reset (clear) the PCM (Computer). HTH. -Jim
