Most of the time, yes, unless it is flashing. A check engine light can come on for something as minor as an oxygen sensor going bad. Most manufacturers use the "Steady" for minor things and "Flashing" for serious things.

How do you reset the check engine light on 1997 ranger?
Remove the battery cables for 5 minutes, should do it. Then the computer will reset and relearn after driving again. If a major fault was present before, it will return via the check engine light. If you need an inspection, then unhooking the battery for 5 minutes and driving maybe 20-40 miles and then going for inspection may do the trick. There is a small window where the check engine light hasn't come on yet and the IM monitors are mostly ready for inspection.....just before the check engine light comes on again. It will pass, in this window. But when the check engine light comes on again, it will not pass.
