Car Sensors and Their Functions in an Auto Engine

Car owners must know the various installed in their vehicle's engine or the value they provide. 

FREMONT, CA: Modern autos are equipped with different types of sensors. There are many of them available in the market, like the throttle position sensor, TPMS sensor, and many more. These sensors are placed into their engines to make sure that the owner can detect and prevent potential problems before they become costly repairs. These car engine sensors also guarantee that the vehicle is running as efficiently as possible.

Several owners are unaware of the various sensors installed in their vehicle's engine or the value they provide. 

Having knowledge about how these pieces of equipment work is crucial for car owners. Here are some of the prominent car engine sensors used in modern vehicles that will help them to understand its function:

The Mass Air Flow Sensor (MAF)

The mass air flow sensor (MAF) can be defined as a computer-controlled sensor that determines the volume and density of the air sucked by the engine among the several types of sensors used in cars. As a result, it guarantees that a proper amount of fuel is used to achieve optimal operating settings. If this sensor fails, the vehicle may stall, resulting in higher-than-normal fuel use.

The Engine Speed Sensor

The engine speed sensor is installed to the crankshaft and measures its spinning speed, which regulates the engine's fuel injection and timing. There are several ways through which an automobile engine can suddenly halt, and this sensor will keep drivers safe.

Oxygen Sensor

The oxygen sensor determines whether the fuel is burning rich or lean by measuring the amount of unburdening oxygen available in the exhaust stream. A defective oxygen sensor will lead the automobile to jolt and idle poorly and consume a lot of fuel.

Fuel Temperature Sensor

The fuel temperature sensor is a sensor that guarantees that the car's fuel usage is as efficient as possible. When the fuel is cold, it is denser and burns slower, and when it is warm, it burns faster. When the automobile runs out of fuel, several automotive parts are destroyed, so this sensor ensures that the correct amount of fuel is injected to maintain the vehicle running smoothly and efficiently as possible.
