I recieved a check engine light (CEL) the other day for P0139, P0137. After jacking the car up and checking the O2 sensor I noticed some of the wires on the O2 sensor were frayed. I figure that was the problem. I also have a Berk Test Pipe and T1R O2 sensor fix extension installed. Is it possible to splice and re wire the original O2 sensor instead of buying a new one? Thanks for the replies!

 

yes i suppose so as long as the wires are the same gauge as stock.
