the light is a warning to you that something is wrong and your engine is not operating correctly and needs to be serviced soon. Most times there is a part of the emissions systems that set it off, like a bad sensor somewhere. You will need to get the CODES read. The codes are then converted to a diagnostic problem and then the parts of that system need to be analyzed to see which one is not operating. I will ask this....did you just recently get gas? You must turn the gas 3 clicks when you put it back on to make sure the correct pressure is in the gas tank otherwise you will get a check engine light. So go check your gas cap and if it is tight.........then you will need to take your car to a place liek Autozone and they will put a diagnostic scan tool on your car usually under the dash under the steering column and pull your codes. From there it is up to you where you decide to get it fixed, either by yourself or a garage. By the way after you tighten the gas cap you will need to drive some miles AND go thru a few stop and start cycles with the engine befoer the service engine light goes out if it was a gas cap issue. The light will not automatically turn off after you tighten the cap.
That is what the check engine light is for. It informs you of a failure.
A flashing check engine light is an indication of a severe engine misfire.
No, low gas cannot cause a Check Engine light to turn on. There would have to be a problem within the engine or the engine wiring for that light to come on.
Yes, it is possible as you may have a miss. That miss would turn on the check engine light.
Probably because you need to check the engine.
Yes it can.
The check engine light comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, a check engine light is lit when there is a problem in the emissions or somthing that is affecting the effectiveness of the emissions.
If it has a downstream O2 sensor the check engine light will come on but if it does not the light may not come out. In most instances it will set the check engine light.
That would be the check engine light.
There are pages of things that will turn the check engine light on. You need to have it checked for codes.
A quick way to reset the check engine light would be to disconnect the battery for a short while
If the check engine light is flashing at 1 second intervals , an engine cylinder misfire has been detected
