A while back when i was installing my headers, i accidentally pulled the plug that connects to the radiator overflow. I started the car and noticed a code. I plugged the plug back in and it stayed on. I tried using a scanner (OBDII), but it couldn't find the code to clear it. Any ideas on how i can clear this damn code?
 
Is this a PCM DTC code or a dash warning light?

For the dash warning light, look inside the coolant overflow tank. There's a magnetic float that's stuck in the down position. Try to knock it loose.

It may be coolant water logged and will not float. The options are to disconnect the sensor electrical connector or buy a new overflow tank.
