If a check engine light is appearing when the car starts then the ECU is receiving an alert from somewhere in the engine. The computer should receive a diagnostic test which will provide an answer as to why the check engine light appeared on the 1997 Honda Civic.
check, plugs, coil, distributor
There are multiple reasons. Have the ECU scanned and that will tell you where to start looking and what part is being effected.
take it to the autozone they check the engine light for free
Check the fuses.
The Check Engine Light comes on when the ECU has detected a problem with the emissions system. Have the ECU scanned with an OBD2 scanner to retrieve the code that has been set. That code will tell you where to start looking for the problem.
This task requires an OBDII code reader. Your mechanic will have one or you can buy a cheap one from your local parts place.
Check your brake fluid level!
If the check engine light is blinking that means an engine cylinder misfire has been detected

I have the same problem with my 1997 civic Dx
On a 1997 Mercury Mountaineer : The " CHECK ENGINE " warning light is just to the left of the battery voltage gauge
A flashing check engine light is an indication of a misfire.
There is not one sensor. All the ECM sensors are tied to the check engine light.
Not in Massachusetts
If the check engine light is flashing at 1 second intervals , an engine cylinder misfire has been detected
If the check engine light is blinking that means that an engine cylinder misfire has been detected
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
Emmissions problem. HAVE THE ENGINE CHECKED!
With a scan tool.
By bringing it to a trained mechanic so they can check the engine is running properly (which if the light is on it's probably not)

It is very easy to reset a check engine light on a 1997. The light can be reset by putting the restet tool into the diagnostic port. The diagnostic port is located right beside the hood release latch.
