Engine Fault Indicator, What does It Mean?

| |

The warning light of the engine can be turned on for several reasons, and although not all of them are serious, it must be taken into account and take the car to the workshop.

When a car starts, many things happen. Suddenly, the engine comes alive, and the fuel begins to explode in the cylinders and causes everything to start. Normally, everything works without more problems, and the motor action makes us move and arrive without problems at our destination. But all those things that occur in the engine during operation wear out the elements that make it up, and although they are designed to withstand conditions for a long time, sooner or later, things start to fail. And then, the engine fault warning appears, to the driver’s horror.

What is happening when the engine fault warning light comes on? Is it bad? Should we stop the car right away and call the crane, as indicated by Sheldon Cooper in that episode of The Big Bang Theory, or can it be followed without more, as Penny said? Well, the truth, better to devote all our attention because it may be a slight gas measurement problem, or it may indicate a problem that leaves the car unusable. We are going to see the reasons why you can turn on the warning light of your car engine.

Reasons why the engine fault warning light comes on

It is important to know that there are several reasons why the engine fault warning light can come on. Normally, the reasons detailed in the car’s instruction manual. Also, the engine fault indicator can illuminate in several colors, and each of them can indicate a different fault and its severity. Besides, the light may start to flash when the problem occurs, and perhaps the car may experience some strange behavior that is easily detected.

  • Power loss: If, in addition to the illumination of the engine fault warning light, the car loses power, the engine may have activated the emergency mode and is requesting that the car stopped. It is time to search the site to stop safely and call the crane to have it checked immediately at a trusted workshop.
  • Temperature sensor failure: A temperature rise can accompany the engine fault indicator, so you have to stop and call the workshop to pick up the car with the crane.
  • More consumption than usual: If an increase in fuel consumption is detected, it may be an injection failure. This problem may be unimportant at first, but it can go further and cause a more serious breakdown. There may also be a power loss, so as the problem is detected, it is better to take it to the workshop and forget about future consequences. It could also be there is a problem in the flowmeter or combustion, so before the ignition of the engine warning light and the power loss or more consumption than normal, the car must take to the workshop.
  • Electrical fault: The spark plugs can be damaged and cause bad combustion, which will affect more smoke emission and other problems that can damage the catalyst and cause a more serious breakdown. It may also cause the warning light engine trouble the spark plug wires, which also replaced periodically.

Whatever the problem you announce, more or less serious, you have to pay attention to the engine fault warning. Possibly nothing strange is detected in the car when it started, but do not forget about it and take the car to the workshop as soon as possible. It may be a small breakdown, but this only means that it can be fixed in time and avoid a more serious breakdown.
