I keep getting these codes. I have researched and know that they are for the Heated O2 sensor,(behind the cat) and the Alternative fuel sensor (where the heck is that?) O2 Sensor has been replaced twice, code keeps coming back. Checked fuse for 02 sensor, suggestions? Can one cause the other 2 look bad?
