I just replaced my all my 02 sensors on my car, do I have to run my car for some time for the codes to go away....
you can unhook the negative battery cable for 15 minutes,and then hook it back up.that will clear the codes you have.don't know why you replaced all the 02 sensors?the codes you have,don't have anything to do with them?if the problem is/was not fixed,then the light will just come back on.why did you replace all the 02 sensors?
