something that affects the emissions.
HJave vehicle scanned to determine the problem
Yes
Any engine or transmission sensor could cause the light to turn on. Many auto parts stores will retrieve stored codes from the computer for you, and suggest possible troubleshooting steps.
It could.It could.
Check the engine thermostat.
assuming you mean the check engine light, or the picture of the engine. A good rule of thumb regardless of manufacturer is that if the check engine light FLASHES, it means there is currently a serious engine (or emissions) problem that could damage the vehicle. Recommend you take it in to a dealer or other good garage.

Check the engine. ===================================================== There is a problem with something that effects the emissions of the engine You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem
The engine computer had detected something wrong somewhere in the engine management system. This could be an O2 sensor or any number of things. Take your car to a shop and have your car scanned for fault codes to see what the problem might be.
If the check engine light is on, use a code scanner to find out why.
The problem could be many things. With the check engine light coming on, it could be an internal issue in the engine, or broken engine mounts causing the vibrations. The shaking could also be caused by a separate issue from the engine, including a loose tire, or an out of balance tire, or bad suspension.
That varies with the problem. Could be immediate, or could take a week.
