When should I be worried about check engine light?
Unlike a Temperature or Oil Pressure light, a Check Engine light is usually not an urgent, “Stop right now or you may cause permanent damage!” type of situation, unless it is flashing. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
Will a dealership buy my car if the check engine light is on?
Most dealerships will use the check engine light malfunction as an excuse to pay you less than the car may be worth. Be ready for a very low offer for the trade in. Your research will show the dealer you will not be taken advantage of.
Is a check engine light serious?
The check engine light — more formally known as the malfunction indicator lamp — is a signal from the car’s engine computer that something is wrong. If the light begins flashing, however, it indicates a more serious problem, such as a misfire that can quickly overheat the catalytic converter.
Can low oil cause the Check Engine light to come on?
The engine check light can turn on for a number of different reasons, but a low oil level is typically not one of them. Being low on oil is a serious problem, but it will not trigger your check engine light. It will, however, cause the oil light in your dashboard to turn on.
Why does my check engine light come on when I accelerate?
A loose fuel cap is one of the most common reasons why the check engine light turns on. The cap is a crucial part of a car’s fuel delivery system. It notably prevents gasoline fumes from leaving the fuel tank, and it helps keep the whole system under the correct pressure.
Can bad spark plugs cause check engine light to come on?
If your spark plugs are worn or faulty, they can cause your engine to misfire, making it run rough, and illuminating your check engine light. Similarly, if you have a faulty ignition coil, it can also trigger the light, as can bad spark plug wires.
Can you turn off the Check Engine light in a car?
You can also typically use these devices to tell the computer in your car to turn off the check engine light. This should only be done if you’re sure the issue has been fixed, but the light wasn’t turned off––otherwise you’re just ignoring a potentially serious problem.
