You have an heated Oxygen sensor. 2 of the wires heat up the sensor and keep it at a certain temperature, it is turned on and off by the computer. The other 2 are use to send a very low voltage reading back to the computer to tell the computer if the engine is running rich or lean. I don't have a diagram to tell you which wire does what but you can get a manual and that should give you the information that you need and tell you how to trouble shoot it to tell if the sensor is bad or not, you may want to look for a wire laying on the exhaust, I have found wires burnt and lay on the metal.

They are all located on you exhaust system. Start from you exhaust manifold and follow the pipes down to the tail pipes . You will see the sensors (4) they are screwed into exhaust pipes and they have wire connections on them (Kinda Looks Like a spark Plug) they wires are unusually colored in white black and grey. Good Luck contact if you need more information
