If you are referring to the diagnostic trouble codes (DTC), you can go to your public library and check out a Haynes or Chilton's Repair Manual for your vehicle. Chapter 6 in either book will have instructions on how to retrieve the codes, what the codes mean, and how to fix/repair/replace the component(s).
You will need an OBDII scanner to retrieve the codes. WalMart has some for about $70 if you want to buy one. Otherwise, you can go to AutoZone and have it scanned free.
