Why Motorists Should Pay Attention to the Engine Light

Car damages and faults are phenomena that are not pleasing to all the car owners. Sometimes, it can happen when you are in the middle of the trip, causing you a lot of headaches. It is advisable that you should take your damaged car to a car repair should but there are problems you can fix on your own. You don’t necessarily need the input of a mechanic to check the engine light because you can do it by yourself. 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. You should ensure that the air filter is clean to reduce the vulnerability of MAF. Some of the roads that affect the mass flow sensor include dusty and dry summer roads as well as snowy and icy 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. 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.

Malfunctioning oxygen sensors could also trigger the engine light. Remember that a faulty oxygen sensor could lead to inaccurate data on the computer; hence a decrease in the gas mileage. The sensors can be either two or four, depending on the type and model of 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.

The other reason to check the engine light is that there could be a fault in the alarm system. Ensure that you get the best installer who will do a professional job to avoid spoiling your car. Choosing the best alarm installer can be a challenge. Lastly, it could be caused by a dead battery; hence you should replace it as soon as possible.
