One of the challenges car owners face is a defective car, either in the engine or a damaged body. Sometimes, it can happen when you are in the middle of the trip, causing you a lot of headaches. Although you should take your car to an auto repair shop; there are some issues you can fix on your own. One of the areas that do not require a lot of expertise is the engine light. Read on to learn some of the things that trigger the engine light.
The first reason why you should check the engine light is that there could be a failure in the air mass flow sensor. If you notice that the air filter is not too clean, you can replace it with a genuine option. It is important to note that the mass flow sensor is at a higher risk at snowy and icy roads and dusty and dry summer roads. Some of the issues caused by a faulty MAF are: increased emissions, low gas mileage, stalling of the car, etc. Besides, you should check the engine light because the spark plugs could malfunction, causing them to misfire.
The other reason why you should check the engine light is that the catalytic converter could be faulty. It is worth noting that the car can still function without a catalytic converter, but it is a better idea to keep it plugged in. It is also likely that the gas cap could be faulty; hence you should check the engine light. Although it is not threatening, you should check it first when the engine light comes on.
The other reason why you should check the engine light is that the oxygen sensors could be malfunctioning. Apart from a decrease in the gas mileage, a fault in the oxygen sensor could also lead to inaccurate data on the computer. By using a scanner, you will be able to identify the sensor that requires a checkup irrespective of the number of sensors in your car. Moreover, the engine light could signal a fault in the spark plug wires. Apart from low performance, a fault in the spark plug wires could also lead to a rough idle as well as reduced gas mileage.
It is also important to note that an after-market alarm system can prevent the car from starting if not correctly installed. Ensure that you get the best installer who will do a professional job to avoid spoiling your car. If it is your first time, the chances are that you will find difficulties getting the best alarm installer considering that there is a mammoth of choices. The other reason why you should check the engine light is that you could be having a dead battery.
