08 endevour o2 sensor wiring diagram

A 'bad' O2 sensor will not blow fuses, the heater goes open circuit. Your wiring can blow fuses.
Look for damage to the loom alongside the engine mount and exhaust mount.

posted 3 times now and forget to say FRONT SENSOR>
right, not the Rear 02 sensor....?
and still no engine stated.!
nor country, (USA calif, usa FED, or canada)
strike three you are out.
sorry.
there are 3 engines,
based on all 3 engine schematics, my wild guess
is 7AFE engine. (the brown wire clue) 1,8L
4AFE (1.6L)
or 1ZZFE engine, DOHC 1.8L

wire colors differ between O2 manufactures
Bosch sensor colors are different then Denso and so on

they are color coded . Black to Black . Gray to Gray. White to White. There may be more than one white wire you can mix them up and it will still work correctly

You never use a Universal Oxygen Sensor & have to solder it in

Makes no sense

Buy an NTK from Rock Auto.Com & just plug it in

Front # 24169
Rear # 24546

O2 sensors just plug in.

Why do you need a wiring diagram for a O2 Sensor? They are 4 wires and when you replace the sensor, you get a OEM. If you are going to get a Universal, it comes with a wiring diagram (GREY go to WHITE) and Black to Black

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.

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

Try autozone.com. There are free diagrams in the repair section.
If you have a new ACDelco pig tail there will be letters on the plug (don't know if aftermarket plugs would have the letters). A wire diagram should show what letters go to what color wire.
If I'm not mistaken,
A=Tan
B=Purple
C=Black
D=Pink
(depending on which O2, the purple and tan wires could have a white stripe)
If there are no letters on the new plug then check the O2.
Also to be sure, the plug goes in one way, You should have at least one more O2 that you can check and see what wire goes where. They will all have basically the same color and plug into the O2 in the same way.
