Originally posted by Bob Blaylock: Unless you have acess to an OBD-II scanner, you have no way of knowing the difference. The CEL is a “Boy who cries "Wolf!'”. Because it so often lights up to indicate minor problems that can safely be ignored, it is useless as a means of warning for severe problems that require immediate attention.I agree. Thats why I wish car companies would put a simple little LCD panel on the dash or under the hood that would display the error code that is causing the CEL to come on. How much could one of those displays cost? $2.00? All that would be needed is a display like the stereo or clock has. To me, that's what ON-BOARD Diagnostics should be.
