I just finished my passenger side wire tuck and had to extend all 6 wires in the harness clip. Now I am throwing an Autozone code P0131, which says it is a Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) Circuit Low Voltage code.

 

Did you extend them properly with solder and heatshrink? Have you double checked your work? Have you compared you work to a wiring diagram.

 

I don't have a wiring diagram. But I use solder and heatshrink. Is the O2 sensor even related to the harness I just tucked?

 

same problem i have tried a number of things to fix this have you checked your #15 fuse under the dash?

 

You could have effected one part of the harnesses attached to the O2 sensor, that specific harness usually runs infront of the trans.

 

did you use the same size wire?

 

yeah i used the same size wire, i relocated the engine compartment fuse box to the trunk and i do think that that is what has caused my problem. im trying to find a new harness to try to eliminate possibilitys.
