I assume this is the check engine light, it is a picture of an engine and it is yellow. If that is correct please read on, if not let me know. The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.
When the Check Engine light (or Service Engine Soon or small picture of an engine) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the electronic system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.
I DID THAT ON 10-19-11 AT AUTOZONE, WHICH IS WHY I HAD THE OIL CHANGED TODAY 10-20-11, BUT THE LIGHT IS STILL ON, ALTHOUGH THEY SAID I WAS 4 QUARTS LOW IN OIL. WHAT ELSE COULD IT BE...PLEASE HELP I DONT KNOW WHETHER TO CONTINUE DRIVING THE VEHICLE OR NOT BUT IT DOES SOUND DIFFERENT WHEN I START IT UP. IT SOUNDS LOUDER LIKE A TRUCK OR SOMETHING. THANK YOU.
You have damaged the engine, the noise you hear is due to low oil pressure likely. This is not a yellow indicator light then? I would not drive it anymore until you have the noise checked.
If this is the change oil due light then it must be reset, that reset may not have been done by the shop that changed the oil. Any dealer will reset this light for free.
THE LIGHT IS A YELLOW PICTURE OF ENGINE AND IT RIDES VERY GOOD. ITS NOT TICKING OR ANYTHING. ITS LOUD WHEN YOU START THE CAR, BUT THATS IT. JUST STILL WONDERING WHY THE LIGHT IS ON. DO YOU THINK I SHOULD TAKE IT TO A DEALER OR ELSEWHERE. WILL THEY CHARGE ME TO TELL ME WHATS WRONG OR
The Yellow light is the Check engine lights. You should have the electronic control system tested as when ever this light is on a trouble code is stored in the computers memory. At this point it is better that the dealer do this test as it seems the Autozone you went to doesn't have a clue to the cause of the light. This is not a oil change light or any type of "service due" light.
