Engine coolant temp sensor. I would check codes if you have a ECT code replace the sensor. does the check engine light come on with key on engine off, If it doesn't replace bulb. If the engine light works check fuel preasure,
you have a cylinder misfire
unhook the battery for about ten minutes
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.

The check engine light comes on at start up for a bulb check. If it stays on with the engine running the computer has detected a malfunction. You need to have it checked for codes.
On an 11 year old car I would suspect a possible vacuum leak. Check all the vacuum hoses under the hood. Can also be a defective EGR valve. Are you sure the Check Engine light is working? This should trigger the light. Turn on the ignition without starting the engine. Look see if the CE light is on.
There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.
If you are talking about the dash lights , check your tail light fuse . they are on the same curcuit
check wiring from battery to wiring harness to fuse (check fuse also) to harness to brake light. Check ground, too
Have vehicle scanned to determine problem and have codes cleared
hit the brakes and have someone tell you if they light up or not only way to do it
