The wires on mine were burnt. PO, or whoever worked on it, didn't properly route the wires around the top of the valve cover. Instead they were laying on the exhaust manifold all crispy and crunchy.
Yesterday I was like, let me troubleshoot and fix these o2 wires and sensors so I feel better about getting something fixed. Then, boom. My transmission started working right after I replaced that fuse.
So, if that fuse on yours is blown the culprit could hopefully be just some shorted out o2 wires blowing it.
It's interesting to me that the same fuse that powers the o2 sensors powers that egs.
