Replaced secondary o2 and still getting code 65
Ok I installed a new secondary o2 sensor and I'm still getting the same code 65 secondary o2 sensor code. Is there a fuse that might be blown tha is connected to the secondary o2? Also did I wire the new o2 in correctly? Green=signal ground, White2 signal, 2 black=heater. What could be wrong?

no, I'm using a test pipe but I'm not getting the catalyst effeciency code, I'm getting a secondary o2 circuit code.

Did you have to rewire or did it just plug in? There are 4 wires (2 white and 2 green). Just keep mixing and matching untill it works (sounds ghetto but works). Did you reset the ecu after you tried? What kind of 02 sensor you using, stock???
