The dealer would have that exact spec for your car. Do you have any friends who are in the auto repair business or that work at an Auto Dealership? The car you have is so new that there is no repair manual out yet to cover it. I have called Chevy Dealership Parts departments before to ask questions and it depends on the person on the other end of the line, as to weather they will give you the right info. Usually they will because it means they could sell you a part or some service work. Try calling and asking or even talking to a service writer or mechanic at a shop. You'd be suprised at what you might find out.

The wiring diagram shows the wiring color code, Power rating and connector plug used. The wiring diagram explains the vehicle's electrical connections with color code. It's a bit complicated to understand.

O2 sensors wiring diagrams


Locate the wires running off from the O2 sensor. There should be two. The black wire is the ground wire. The other wire, which may vary in color, supplies power to the sensor.

  • 2 Connect the power lead to the corresponding connector on the chassis's wiring harness.
  • 3 Connect the black, or ground, lead to the corresponding connector on the factory wiring harness.
  • 3 wires, "how do i wire it" are simply explained. all universal 3 wire o2 sensors will have 2 wires one color, the other wire a different color. the 2 that are the same color are ground and power for the heater and it doens't matter which one is which. so ground to the motor, power from the gray wire on the fuel pump, or anywhere you want to pull 12 volts while the car is running. i have a dedicated fan relay that doesn't use the ecm and runs off the key, so thats where i went. the different color wire goes to the stock sensor wire, it's the signal.

    I need wiring diagram for the o2 sensor on the passenger side after the convertor, i ran over something and it snatched the connectors off.so i need to know which colors to match the for wires too.


    these wires are colour coded on the vehicle so if you are using a factory o2 sensor that your trying to wire then you just have to match the wire colours to each other

    What wire on the o2 sensor is the correct one to connect a air/fuel ratio gauge on a 09 silverado 1500 with a 5.3


    You can not connect to the heater wire or ground,
    so I guess the output or sensor wire

    I wouldn't do that, because your not supposed
    to load that wire, or you run the chance of ruining
    the O2 Sensor.

    Forget it
    Why do you need to know AFR anyway !

    Weld in a separate bung for that device

    I have a 1998 chevy malibu what wire for the o2 sensor is the signal wire and theres four to choose from


    On the front O2 Sensor, the signal wire s Purple. On the rear O2 Sensor, the signal wire is Purple and White. (You will probably have to look at the wire colors on the main harness side of the O2 Sensor connector, not on the sensor itself.)

    with an ohm meter you can determine which one is the signal wire by the voltage fluctuating from .800 mv to .150mv
