Do you want to ask your questions about the injection light? So you are in the right place. In today’s article, I will explain how the injection light works, why it is on, some signs that the car shows in case of a problem, and much more.
Only those who have seen a panel light on know how desperate it is. Among so many possibilities, the fuel injection light is one that needs special attention from the driver.
And many must wonder why these lights come on but rest assured because even giving all assistance to the vehicle and doing all preventive and predictive maintenance, the car can have some problems. Sometimes it’s not the driver’s fault and the defect could be the factory.
Amazingly, the injection light is one of the most common car problems, but drivers end up not paying enough attention.
Still without insurance for your car?
And it shouldn’t be like that, after all, the injection system is extremely important for the perfect functioning of the vehicle since it is the part responsible for commanding the fuel supply and engine management, that is, full attention to the injection light lit.
If you are not yet familiar with car dashboard lights, read this text here and get to know them all. You now have the information you need to learn more about the injection light.
What is the injection light for?
When you put the key in the ignition and turn it, but without starting the engine, the electronic injection center is activated and checks if the system is in perfect condition, so that the driver can start the car.
When the driver puts the key in the ignition but does not start, a command is given and the fuel pump starts. In this way, the center is able to perform an analysis and check if there is electrical continuity and if all sensors and actuators are working perfectly.
Our point here is the fuel injection light on, and it is quite simple to identify it on the dashboard, as it is located on the instrument panel and has the shape of an engine, triangle, or spoke, depending on the model of each car. After all, there is not just one way of representing the system on the car’s dashboard. As for the color, it is possible to identify it as red or yellow.
What does it mean for the injection light to be on?
The hypotheses can be varied, but basically, the fuel injection light is on because there is a problem in one of the parts of the electronic injection system.
As this is a very complex system, it is difficult to specify what the problem is without the eye of a professional expert in the subject and without the help of an automotive scanner.
To identify the problem, turn off the vehicle for a few minutes and turn it on again after a few minutes. It may be that this problem is not permanent, but intermittent. However, if it persists, take the car to the mechanic.
If you notice the fuel injection light on permanently, take the car to your trusted mechanic as soon as possible – as long as he has knowledge of the subject to check the problem. Otherwise, opt for a specialist.
It is important that it is a qualified professional, as the problem will only be identified through this scanner, which can read the vehicle’s electronic injection system.
The most common problems with the injection light, diagnosed by the scanner are: dirty electro injector, spark plug, spark plug wire, or even adulterated fuel.
In the latter case, the fuel of bad origin interrupts or harms a system that is made to regulate the perfect balance between fuel and air. There is no room for errors.
Signs that you may have an engine problem
In addition to what causes the injection light on, it is possible to understand some behaviors that the car may have and that are symptoms of this problem, such as difficulty starting the car, excessive increase in fuel consumption, loss of power, and acceleration of the engine. slow running.
If you notice any of these symptoms, stay tuned, as your car may be giving the first signs that something more serious is about to happen.
What if the injection light is blinking?
It is normal that when you put the key in the ignition and turn it on, all the lights stay on for about two seconds. If this persists after this time, it means that some type of problem has been registered with the electronic injection system.
Sometimes it’s nothing too serious and it could be adulterated fuel, but you need to keep an eye on it. In this case, it is better to take the car to a mechanic to empty the tank and, later, put in a quality fuel.
Another possibility of the injection light going on and off is a simpler problem, something in the reading of the lambda probe, which is next to the exhaust manifold.
It usually happens because of poor contact with the sensor plugs. A mechanic can solve this in a short time and at a low cost, sometimes only labor, avoiding problems such as the injection light on.
Finally, another problem that can occur is in the catalytic converter. The part may not be doing the job properly because it is clogged. If not, the hypothesis is that the piece is not fulfilling its function of transforming toxic gases into less polluting gases.
Is it dangerous to walk with the injection light on?
The injection system is so intelligent that even with faults it is possible to drive. However, the chance of an electrical failure increases significantly. Therefore, it is necessary to keep an eye out and not let this situation last for a long time, to avoid further headaches.
If you understood the injection system and what causes the injection light to come on, you must have also realized how important it is to keep your car protected, right? Count on us to avoid these problems and the headaches that come with them.
