It is on the Driver side of engine in between the COP's (Coil on plugs) simply unplug the wire use a 19 or 3/4 deep well socket and unscrew it and put it new one... The whole process should only take 10-15 minutes.

You can remove the NEG battery terminal for 10 minutes and it will clear. Or go to Autozone or Oreillys for a free scan, find out why it came on, then have them clear it with their scanner.
