First of all what is the exact code number you have? The code is a starting point not a replacement code.

Its going to be the one on the left side by the cat unplug the connector to it. Then measure the sennsor side of the connecotors accross the dark green wire and the black wire with a white stripe. You should measure 12.1-14.8 ohms do this when its totally cold and has sat overnight.
