You are of course correct, and I plan to have the sensor replaced. However, I was discussing this with a co-worker and he mentioned the ability to reset the car light (which would be useful if you’d done the required work yourself and now needed to reset the light.) I am merely curious as to whether I can read the codes this way, and whether the reset works this way if I ever have someone do the work who doesn’t have the ability to reset the light in the normal way.
