Today’s modern automobiles have a variety of sensors. These sensors built into their engine to ensure that the owner can identify and prevent possible issues before they result in breakdowns can result in expensive repairs. These automobile engine sensors also ensure that the vehicle is operating at its most efficient.

The Mass Air Flow Sensor (MAF)
From different types of sensors used in cars, The Mass Air Flow Sensor (MAF) is a computer-controlled sensor that calculates the volume and density of the air taken in by the engine. This in turn ensures the right amount of fuel is used for optimized operating conditions. If this sensor is faulty, the car may stall and the fuel usage will be higher than necessary.
The Engine Speed Sensor
Engine Speed Sensor is attached to the crankshaft and monitors the spinning speed of the crankshaft, which controls the fuel injection and timing of the engine. There are many ways for car engine to stop suddenly, and this sensor will prevent that for drivers.
Oxygen Sensor
The Oxygen sensor measures the amount of unburden oxygen that is present in the exhaust pipe and will indicate if the fuel is burning rich or lean. A faulty oxygen sensor will cause the car to idle poorly and jerk as well as cause high fuel consumption.
Manifold Absolute Pressure Sensor
A Manifold Absolute Pressure Sensor, or MAP, senses the engine load. As it is mounted on the intake manifold it can measure the difference between the intake manifold pressure and outside. This is important for the engine to be able to adjust the fuel injection based on the change in pressure.
Spark Knock Sensor
A spark knock sensor ensures that the fuel is burning smoothly and not detonating (exploding erratically). Detonation can cause the head gasket to fail, piston lands to crack and rings to break, as well as possible rod bearing damage.
Fuel Temperature Sensor
The Fuel Temperature Sensor is another sensor that ensures your cars fuel consumption is at its most efficient. The colder the fuel is the more dense and the slower it burns while when the fuel is warm is burns faster. There are many car parts will get damaged when the car runs out of fuel, so this sensor ensures that the right amount of fuel is injected to keep the vehicle running smoothly while being as efficient as possible.
Voltage Sensor
Another important part in car sensors list is the Voltage Sensor. This sensor manages the idling speed of the car and ensures the speed is increased or decreased as necessary.
Coolant Sensor
The coolant sensor is probably the most important sensor. Because the computer relies on its input to control other functions. For example, activating or deactivating the Early Fuel Evaporation (EFE) system, spark advance and retard, EGR flow, canister purge etc.
This sensor is generally located on the head or intake manifold. Because it is such an important sensor, it can be a problem if the sensor is faulty. If the sensor is faulty, there will be some symptoms like poor fuel mileage, stalling. So the point is that you have to make sure that the coolant sensor is not defective.
Vehicle Speed Sensor
Just by hearing the name, you can pretty much assume its functionality. But we will explain it anyway. The vehicle speed sensor has the ability to determine the speed of the wheels. It is a kind of tachometer.
Throttle Position Sensor
The throttle position sensor is used with EFI (electronic fuel injection) and feedback carburetion. It notifies the computer about the rate of throttle opening. Furthermore, it tells the computer about the relative throttle position.
The throttle position sensor is mainly a variable resistor. It changes resistance when the throttle opens.
It is not difficult to know the symptoms of a faulty throttle position sensor. When there is a stumble during acceleration, you will know that your throttle position sensor is defective. It is the main symptom of a defective throttle position sensor. When you replace the sensor, do not misadjust it.
Camshaft Position Sensor
The control module uses the camshaft position sensor. It can indicate the position of the number one cylinder. In order to start the sequential fuel injection, the control module uses this piece of information as a reference point.
