Nissan Repair: 02 sensor

Question
I have a Nissan 2002 that needs an 02 sensor.  I'm looking to purchase a new one, do I get heated wires? Do I get four or five wires?  does it matter will they all fit?  It is for a 3.3.

Answer
Hi Kevin

Sorry for the late reply.

Usually when you buy an O2 sensor, the wires and harness comes with it. Just ensure that you get the proper sensor. Some models have up to 4 sensors, left bank, right bank, sensor 1, sensor 2, etc.

I don't know how you determined that the senor needs replacing, however if you used an OBD reader, it should have indicated which one it was on the display.

Hope this helps -
