O2 Sensor Wiring?

[John]

1997 honda crv
2.0L

I know its not advisable to use universal o2 sensors, but im so broke I dont have much of an option. The extra gas is hurting too, both my upstream and downstream are completely out.

Im not sure which wire is for what on this sensor, let along the crv.

Any thoughts?

Pic included, thanks in advance

See if this link helps you if not just let me know and I will do some more research for you.
Note- make sure you don’t cut the factory plug off the harness side. Pull the old sensor and cut the plug of the old sensor and wire it into the new sensor.

Thats the thing these 02 sensors dont have plugs or caps, just straight wore out. It helps me kinda but these ones didnt come with instruction on which wires are supposed to be for what. Maybe i should look into getting bosch ones

If you’re broke, why waste money on oxygen sensors that may not work at all? Go to a Honda parts site, find the OEM part, then go to Rock Auto and you should be able to find the exact same part under the manufacturer’s brand. Amazon most likely sells them. They’ll come with the connector. I replaced the d/s sensor in my Accord a few years ago. The Honda part was $75 and the Denso equivalent was $40. Other than a different wire cover, they were identical and the Denso sensor has worked perfectly. Looking on Amazon, the difference between the universal Denso sensor and the one with a connector is $4.

The two white wires are the heater. The gray is the signal ground. The black is the ECU signal.
