    Problems & Issues
    I have a 2004 Honda CRV 75K miles. The MIL lamp recently came on. I took it to Autozone and they told me the code was PO135. I disconnected the battery and changed the front Oxygen Sensor (a/f ratio) I have driven the car several days and the light is still on. What should I do next?
