I don't know
Obvious answer is there is something wrong. We don't know either, That is why when the light comes on, a sensor trips a code that is stored in the computer system of your car and you can hook a scanner up to determine what the code is and pinpointing you to the area of concern. So have the car scanned for the 4 digit codes and post them back here and we can help. Most auto part stores will scan your car for free, just ask
We wouldn't know either, until you go to like Auto Zone and have the code, or codes read. Then post the code back here for more help.
