Guys, I need your help!!! My check engine light came on about two months ago...I took it to my friend, he hooked it up to a computer and told me my obd-II is throwing a primary o2 sensor code...I went to Auto Zone and bought a universal Bosch o2 sensor and hooked it up just as the instructions said...We then cleared the code using the computer. I started my car and the check engine light was off!!! About 2 hours later when I started the car again...the light was back on! I hooked it back up to the computer and it is throwing the primary sensor code again...I figure maybe there is something wrong with the sensor so I took it back and they gave me another one, but after installing it, the same scenario happened!!! Is there anyway to bypass the o2 sensor and if so, how? If not, who should I take this problem to! I thought Hondaland, but I did not want to pay an arm and a leg!!! Any help or advice would be appreciated! Thanks!
