Do codes that trigger the check engine light fall into two groups? One group behaves in such a way that if triggered, the CEL remains on and has to be reset manually. With the other group, the CEL will turn off automatically once the problem is fixed. Does this make sense? Examples?

The CEL will normally turn off after three consecutive passess of the initially failed test. Some tests require certain conditions to be met, so they may not run every time the vehicle is driven.
