Is this check engine light an error?

[Bugeye01WRX]

Hello all!

Just wondering what could potentially cause this. My check engine light has flashed (by flashed I mean appeared and disappeared a split second later) a few times in the 2 years I have had car but never had any issues and had them checked/diagnostic and never shows up anything.

Today however I turned car on and was letting it idle for 1 min as I always do before taking off and noticed Check Engine Light and it was staying on. I turned car off and back on just to double check and it was gone and when driving it did not come back on.

 

If it is not coming up again now, just an error most likely? The only reason I could think of was today I drove over a speed bump a bit fast and the front end of the car (basically the undercarriage under the hood) scraped so unless there is something under there that could have got damaged related to engine or sensors, just an error most likely?

Is the scanner you're using able to pull up stored codes or only current ones?

It will have a stored code. Find out how to extract it. Might be some combination of plugs under the ECU and then it will either flash some random code at you, or display it in the trip counter or something.
