I need some help on a Check Engine Light - 02 Sensor problem. The light only comes on when I drive over 65mph. I checked the OBD and the light code is the 02 Sensor. I checked with Honda and a replacement sensor was about $200! So I went to Advance Auto and bought a Bosch univeral for about $20. I installed the new sensor and cleared the ECU, but the Check Engine light still comes on. Is there something that I am missing? Does it take awhile for the ECU to clear the code (100 miles or something)? Did I buy the wrong 02 Sensor? Do I need to replace something in addition to the 02 Sensor?
