I have a 99-00 si. My o2 sensor went bad this weekend, and now I have a CEL. This is the header o2 sensor, it screws into the header and has 4 wires that go into a harness that clips into a plug in the engine bay.

My question is whether I have to get a sensor for 99-00 Si only, or whether the dx/lx/ex ones will work as well.

Please post if you know, I need one ASAP and am going junkyard scrounging tomorrow.

Thanks.

 

any four wire (heated) o2 sensor wil work.
