    I have a 03 CRV. The check engine light came on and the OBDII code reader stated no activity from the O2 sensor, Code P0134. I've discovered the CRV has a front and rear O2 sensor. How do I go about finding out which sensor is the bad one? Any help would be much appreciated. Thank you.

    If it was me, I would start with one. Get a new O2 sensor, and replace the front one first, and if the code still persists, than change the rear. That way you only buy one sensor. If you replace the front one and the code still persists, than you know it's the rear one, and the front one is still functional and working. Just use that one on the rear.
