I need to find and replace the bank2 sensor but I only need the male end

Hello, so you do not have both ends that were cut still? Meaning you cant use crimp connectors to repair the 4 wires that run to the bank 2 oxygen sensor? Or youre saying that the connector on the sensor side of the harness was lost somehow. I assume by youre mentioning km, you are not in the US, where are you located?

Yeah trying to find the connector itself will be very difficult, the best thing to do is just to get a new oxygen sensor altogether.

Im looking at the wiring diagrams right now, and it showing only 1 upstream oxygen sensor and 1 downstream after the cat, even though this is a V6, is that correct? Or do you have a sensors upstream of the Cat in both banks of the engine?
Service info is showing only one upstream 02 for both VIN #s.

And is the 8th digit of your VIN # a "1" or a "K"?
I dont want to get your hopes up, but Ill take a look and see if I can find you one.

This is what its showing, just one upstream and one downstream 02 sensors.

Can you send me a picture of the harness connector for the sensor you need. I actually might have your sensor here right now, a friend who was retiring actually gave 150 oxygen sensors that are all from the late 90s up to 2004-5 range, Ill take a picture of the connector on these sensors and let me know if it looks correct.

These are supposed to be for an 04 Chevy Impala 3.8L VIN both 1 & K. I have a bag full of them.

Ok it looks like the upstream 02 sensors have a female connector and the downstream (after the Cat) have a male connector as in the pictures above,
This is the upstream (pre Cat) S1 oxygen sensor connector, it is a female connector.

Refresh this page, I posted new pictures.

This one actually has the pins marked on it, B & D and C & A, that pinout is correct according to service info, Send me an email address and Ill contact you on the side, Ill mail these both up to you tomorrow. Not sure how long it will take, I cant imagine it will take more than a few days.
Do you want the Sensor 2 as well? I have no need for all these sensors, I was just going to give them away, so it makes no difference to me if you want both

I just meant in service information they show the harness side of the connectors not the sensor side, and S1 and S2 are both opposite. They just have them listed weird. But service info is sometimes incorrect. This looks all good though

Heres the replacement info for sensor 1, they can be difficult to get out sometimes, try some heat if it feels like its going to strip the threads out of the exhaust manifold.
