Benefits Associated With a Constant Check On the Engine Light
One of the challenges car owners face is a defective car, either in the engine or a damaged body. It can spoil your day considering that sometimes the car can break down in the middle of the journey. Not all the car problem require the attention of a mechanic. Engine light is one area that you can check at home without involving a mechanic. 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 the air filter is not clean, the MAF could be vulnerable. Some of the roads that affect the mass flow sensor include dusty and dry summer roads as well as snowy and icy roads. Ensure that you check the MAF to avoid increased emissions and decreased gas mileage. 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. The catalytic converter should be plugged and checked regularly even though the car can still move without it. Also, the gas cap could be faulty or loose, causing an increase in emissions. If the engine light comes on and the car is not jerking, the first thing to check is the gas cap.
The other reason why you should check the engine light is that the oxygen sensors could be malfunctioning. If the oxygen sensor is not functioning properly, the chances are that there will be inaccurate data on the computer as well as a decrease in the gas mileage. 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. The spark plug wires, which transfer energy from the coils to the plugs could also be faulty, causing the engine light to come on. Apart from low performance, a fault in the spark plug wires could also lead to a rough idle as well as reduced gas mileage.
The engine light could as well be signaled by a fault in the alarm system, which may prevent the car from starting especially if they are not installed correctly. The alarm system should be installed by someone who has adequate expertise. 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. Lastly, it could be caused by a dead battery; hence you should replace it as soon as possible.
