yes it can. if the check engine light shuts off by itself then chances are either the trouble code is a soft code. A hard code will keep the check engine light on until the problem is fixed and the check engine light is reset.
Check on the driverside cylinder head. My engine code is on the head.
When the check engine light comes on it should post a code. Use a code reader to see what the code is and ask again.
and what code does the check engine light say ? go by autozone they will check it for free and get the code.
You can buy the check engine computer and the book comes with it. I know, I bought one. When your check engine light comes on, you plug it in and check the engine and it will give you the code and you look in the book for that code and it gives you the answer.
It is possible that a Subaru Check Engine Code #12 is a bad starter switch. This is usually the starter relay switch malfunction code for Subaru.
The check engine light sets a code for diagnostics and you need a code reader. Most auto parts stores sell code readers and most will check the codes for free.
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.
