O2 Sensor Code Mystery. Help!!!!!
Ok, here's the situation. Before I get started, yes, I have checked past threads but can't find anything just like this. I had a new x pipe and mufflers installed a little while back. The next day I threw...
P0135: Heated O2 Sensor-Heater Circuit Bank 1, Sensor 1.
P0155: "....................................... ...."Bank 2, Sensor 1.
P0161: "....................................... ...."Bank 2, Sensor 2.
*Also: the oxygen sensor fuse keeps blowing everytime I replace it.
(#15)
My questions are: Are these telling me that the O2 sensors all went bad as soon as I changed my exhaust? If the sensors are bad, would that keep blowing the fuse? (maybe the fuse was already blown a while age). If there were just a leak, why would the fuse keep blowing?
The car runs fine. Thanks in advance for any help.

you have a o2 harness touching grounding out.i would look at the left rear,it's the only one NOT throwing a fault.all 4 share the same fuse.the only thing that will pop the fuse is a short to ground.start looking at all the o2's.you have 1 of them either pinched under a sheild or melted together somewhere.
