The other night i ran over something with my car and after like one mile, my service engine light came on. After i got home, i took a look at it and saw that the oxygen sensor was unplugged from the connector. I tried to plug it back, but it doesn't turn the light off. The connector is broken and probably one of the wires too.
My question is: where can i get an oxygen sensor WITH connectors?
Thanks for your help

 

Which connector is broken,one on the o2 sensor or the one from the wiring harness.

 

The one from the wiring harness.
I tried to plug it back in, but the service engine light is still on
I guess it doesn't make contact

 

If it clicked back together then it is making contact.The reason the light is on is the coputer set a code when it didnt see a signal from the o2 sensor.Just go to either advanced auto parts or is it autozone and they will scan it and shut off the light for free.

 

Yeah, but the connector is broken and the wire is dangling loose under the car.

 

What if i reset the ecu? Like leave the battery unplugged for 24 hrs?
Would that fix it?

Resetting the ecu wont help on obdII systems you have to get a code reader to shut it off.The connector that is broken.....if it is coming from the wiring harness you will have to check with infiniti parts to see if they have a repair kit for the connector.If it is the connector from the o2 sensor just buy a new o2 sensor.
