Hi,
You're kind of stating the obvious here, there is always a reason that a code is thrown (not that you can always find it or duplicate it).
But, those reasons can range from a worn or inoperative component, such as an Oil Separator, OČ Sensor or MAF, a Tank of Bad Fuel, or even just a
one-time glitch, such as when you need to reboot your PC. Almost any component using microprocessors (which is really all the DME is) can experience these.
Proper diagnosis of any problem should include resetting the DME. This eliminates the possibility that it may have been such a one-time glitch. If the CEL re-occurs, then you know to dig deeper, that the DME is probably not the culprit.
You decipher the code and move on to those components or conditions (such as possible bad gas, heavy rainfall, etc.) which could be related to that code and try to find that one (either by intuition, experience, component testing, or some combination of all three) which is the cause...
