I got a check engine light come on a couple of days back, and it was there for less than a day before it went blank again. I have a car code scanner, and it came back as P0325 (Knock Sensor problem). Now the fact that the light went out again, does it mean that the knock sensor fixed itself? I checked the code again, and it still shows the same code, but that's probably just because it records the last problem.
I know that the Check Engine light sometimes automatically goes out after a certain number of days, but I thought that would be after 3 days or so.
Should I clear the code, and see if it recurs?
