NO engine Light, no other codes; I had an "Oxygen Sensor INC, up uintil two days ago and it finially went RDY.

Does anyone know which speed sensor is "A"? Someone said it's the right rear?

I tried to Monitor the live wheel speeds while driving to isolate which sensor is dropping out or reading erratically, but my $350 scanner does not have that option. So, I ordered all 4 sensors and going to replace all of them. Does anyone know if the code will just clear after I replace the bad one? It's listed as "Permanent" and can't be cleared with the scan tool. The car also failed California Smog yesterday because of this!

Anyone???
