I just got this code over the weekend (4-3-3). I think it is for a rear knock sensor. I also want to know how serious it is.

I did talk to a couple of mechanics who said that if I continued to use good fuel it wouldn't be a problem, however, when it comes time for it to be smogged the car won't pass, because of the light.

The other mechanic said it could be a false reading, especially if the car appears to be running fine. He said it was not very common to have to replace the knock sensors. If you do have to replace the rear, most mechanics suggest doing front & rear.
