Varieties of car sensors are used in our modern automobiles and each of these sensors has specific car parts they collect information about. See them below!
A lot of people have no idea how their modern automobile is able to sense and alert them about the condition of some car parts. This is why Naijauto.com thinks its best to discuss it in this article. There are varieties of sensors used in modern cars that helps monitor and collect information about the parts they are fitted to. There are some particular 7 among these sensors that are very important for car owners and drivers to know about. Further below, we will be listing and discussing each of these 7 important sensors.
But before we dive in, you should understand that these sensors are built into the engines of modern cars in order to assist any vehicle owner. These sensors do this by monitoring and reporting any issues with each of the parts so that it can be fixed on time to avoid eventual breakdown or expensive car repairs. They also ensure that a vehicle’s engine is running at its most efficient level. Now, let’s get to it.
1. The mass air flow sensor
This is a type of computer-controlled sensor used in a car engine which is responsible for calculating the volume & density of air that is taken in by that vehicle’s engine. It helps the vehicle’s engine to operate at optimized conditions by ensuring that the correct amount of fuel is used every time. When a car keeps stalling and you notice that the fuel usage now becomes higher than usual, there is a huge probability that the mass air flow sensor is faulty.

2. Engine speed sensor
This sensor is always fitted to a modern car’s crankshaft. It helps to monitor the crankshaft’s spinning speed, which then controls the timing and fuel injection of such vehicle’s engine. With this sensor present, it greatly reduces the embarrassment of a car’s engine stopping suddenly.

3. Oxygen sensor
The oxygen sensor helps to determine if the fuel in a vehicle is burning lean or rich. It does this by measuring the unburden oxygen amount present in that vehicle’s exhaust pipe. Whenever the oxygen sensor is faulty, the car might start consuming fuel in high quantity than usual. The car might also be jerking or idle poorly. Funny enough, this same type of oxygen sensors is used in real life gasmasks.

4. The manifold absolute pressure sensor (MAP)
This is the sensor that senses a vehicle’s engine load. This sensor is capable of measuring the outside manifold pressure as well as intake because it is fixed on the engine’s intake manifold. This MAP sensor is very important in helping to pressure change which the engine then uses to adjust its fuel injection accordingly. If you find your car has these 3 symptoms, chances are your MAF sensor is faulty.

5. Spark knock sensor
This is one interesting sensor because it is responsible for ensuring that fuel in the vehicle’s engine burns smoothly. It makes sure that the fuel isn’t exploding erratically (detonating). Little will you know that when fuel is detonating, a lot of harm will be caused to the car’s engine. Harms such as possible damage of the rod bearing, broken rings, cracked pistons lands, and failing head gasket. This is why among all the sensors; the spark knock sensor is highly important.

6. Fuel temperature sensor
Just as one could already notice from the name, this sensor is also very important for any vehicle to have efficient fuel consumption. It basically senses the temperature of the fuel in your car. When the fuel is cold, it will be dense and burn slower while it will burn much faster when it’s warm and less dense.
Just as you might already be aware that many parts of a car get damaged easily if it keeps running out of fuel. So, this sensor helps keep your car running smoothly and efficiently by ensuring that the correct fuel amount is injected each time.
7. Voltage sensor
The voltage sensor is also another important one among the various car sensors. Believe it or not, this small sensor is responsible for managing idling speed of your car. It also ensures that speed is decreased or increased appropriately in your car.
