I have a 2010 G37 Journey. I ran over truck tire debris on the road and it took out my driver side downstream oxygen sensor connection. The harness on both sides are down to the male and female pins but my problem is that I do not know how to match up the wires. The oxygen sensor side has 2 white, 1 grey, and 1 black. The main harness side has orange, black, light blue, and light green. My plan is to connect the wires and heat shrink.

Does anyone have access to wiring diagrams that will help me get the right match? Any help would be appreciated.

The motherlode of Factory Service Manuals is right here:

Scroll down, click on G37, sedan, 2010, viola. PG.pdf (Power and Ground) and where I found the breakdown of the connectors attached below. Hope that helps.

The most common application is to measure the exhaust-gas concentration of oxygen for internal combustion engines in automobiles and other vehicles in order to calculate and, if required, dynamically adjust the air-fuel ratio so that catalytic converters can work optimally, and also determine whether the converter is performing properly or not. Divers also use a similar device to measure the partial pressure of oxygen in their breathing gas.

Scientists use oxygen sensors to measure respiration or production of oxygen and use a different approach. Oxygen sensors are used in oxygen analyzers, which find extensive use in medical applications such as anesthesia monitors, respirators and oxygen concentrator so.

Oxygen sensors are also used in hypoxic air fire prevention systems to continuously monitor the oxygen concentration inside the protected volumes.

how did you know how to match cables if there are different colors I currently have the same problem only that it is in bank 1 color cables on bank 1 are pink red white black and the after market o2 connector is 4 cables black how would i wire this?

You stop reading the colors and read the diagram.

If you look at the diagram it says H.S. with the icon of a connector. This means Harness Side.

So with the locking tab pointing up, you look at the back of the connector and compare the pins to the diagram.

At this point I suggest taking a piece of tape and pen and label the wires once you've identified them.

It makes it much easier at avoiding colors.
