Ok so I would like to know how to test my o2 sensor. I'm throwing the code for bad o2 sensor and would like to fix it. I'm not quite sure if the sensor is bad or not and I would like to be certain before replacing it. dont want to spend that extra $$$ if I dont have to so some helpful times would be appreciated.

Also if anyone knows the wire layout for the plug I would appreciate that to because when I was removing my car the wires pulled out and I'm not sure if I plugged them in correctly. Although I'm pretty sure I did because I did not get a check engine light I would like to be certain about that as well

1sr reset the ecu. then see if it happens again. and make sure the o2 is in good.

 

I have done that. I think it might be because of my new High Flow Cat. Maybe I will re-install the stock one and reset the Ecu and see if its still throwing the code. If so I will probably just go pick up a new one. I'm not really sure how to test the resistance levels on it.

 

yeah it may be thee cat,
