Car Sensors Explained: What They Are, How They Work, and Why You Need Them
In this article, we will learn about some of the different types of sensors used in the automotive industry and how they work.
Engine Speed Sensor
The engine speed sensor is a sensor that measures how fast the engine is spinning. It is usually attached to the crankshaft, which is the part of the engine that connects to the pistons. The engine speed sensor sends a signal to the computer that controls the fuel injection, ignition, and other systems. The computer uses this information to adjust the amount of fuel and air that goes into the engine, and the timing of the spark plugs. This helps the engine run smoothly and efficiently.
Knock Sensor
The knock sensor is a sensor that detects if the engine is making a knocking or pinging sound. This sound means that the fuel and air mixture in the engine is not burning properly, which can damage the engine. The knock sensor sends a signal to the computer that tells it to change the fuel and air mixture or the timing of the spark plugs. This helps the engine run better and prevent damage.
Air Flow Sensor
The air flow sensor is a sensor that measures how much air is going into the engine. It is usually located in the air intake, which is the part of the engine that sucks in air from outside. The air flow sensor sends a signal to the computer that tells it how much air is available for the engine. The computer uses this information to adjust the amount of fuel that goes into the engine, and the amount of oxygen that goes into the exhaust. This helps the engine run cleaner and reduce emissions.
Camshaft Sensor
The cam sensor is a sensor that measures the position of the camshaft, which is the part of the engine that opens and closes the valves. The valves are the parts of the engine that let the fuel and air mixture in and the exhaust out. The cam sensor sends a signal to the computer that tells it when the valves are open or closed. The computer uses this information to adjust the timing of the fuel injection and the spark plugs. This helps the engine run more powerfully and smoothly.
Coolant Sensor
The coolant sensor is a sensor that meas
