Everything You Must Know About Car Sensors


In the era of technological advancement, everyone has heard the term ‘Sensor’ at some point in their life. Continue reading the article if you want the ins and outs of car sensors and their functions.

What is a Sensor?

Any changes in the equipment can be detected, and information about the same is given via sensors. These have been integrated into the automobiles and safeguard the life of the passengers from threats. Every vehicle has different sensors that work in a way that doesn’t pose a risk to the life of the driver and have been discussed as follows:

Modern vehicles have 15-30 car sensors in them. These are calculated, excluding the solenoids. The entire car consists of 70 sensors in total.

How Many Sensors are Present in Car Engine?

Crank Sensor

Crank Sensor

Mitsubishi was the first company that introduced the idea of a crank sensor. Automobiles comprise a crank sensor, an electronic device generally present in the internal combustion engine. The fuel injection is generally regulated with the help of this sensor. In addition, other parameters, along with ignition system timings, are handled by the sensor.

Engine Coolant Temperature Sensor

Engine coolant temperature sensor

The temperature of the engine coolant present in the internal combustion engine is generally calibrated with the help of an engine coolant temperature sensor. The results are sent to the Engine control unit so that the fuel injection and ignition timings can be regulated properly. What distinguishes one engine coolant temperature sensor from another is the installation process that differs from vehicle to vehicle. Poorly working engine coolant temperature sensor won’t inject the fuel in the car properly, and engine coolant temperature sensor replacement would resolve the issues in no time.

Parking Sensors

Parking Sensors

Information related to parking obstacles can be obtained from the parking sensors installed in the vehicles. Some cars have electromagnetic while others have ultrasonic sensors in them. These sensors are called by different names, including park distance control and park assist. The market consists of reverse sensors, and the installation process of these sensors is very simple and doesn’t need maintenance from time to time.

Torque Sensors

A torque sensor, also known as a torque transducer or torque meter, helps measure the torque of the rotating systems, including the engine, crankshaft, gearbox, transmission, rotor, etc. The automobile needs adequate torque, and calculating it isn’t an effortless task.

Manifold Air Pressure Sensor

The manifold air pressure sensor sends a notification to the engine control module on the amount of power the engine has started putting out. The MAP is a significant part of the car’s electronic control system.

Knock Sensors

The primary role of knock sensors is to prevent the engine from detonation or knocking. Detonation or knocking isn’t ideal for the internal parts and leads to costly repairs in the future. Issues in the knock sensor lead to misfires or broken components, and knock sensor replacement is the quickest way to resolve the issue.

Throttle Position Sensor

Throttle position sensor

The connection between the accelerator pedal & throttle body is generally established via electrical connections than a cable. A throttle position sensor calibrated the flab angle of the throttle. The open situation of the throttle is usually shared with the ECM module by the sensor. If there are issues with the pedal and the throttle, it won’t take a ton of fuel inside it, and the sticky throttle starts damaging the engine.

How to Save Money on Sensor Replacement?

After a while, the sensor would start giving issues, and sensor replacements can be expensive. However, you can save a lot of money by getting the sensors from a store selling quality car parts and accessories online like ‘The Auto Parts Shop’ that brings premium quality sensors to you. The best part is every sensor is available at nominal rates.

The Bottom Line

It’s vital to have adequate information about the type of sensor present in the car. Also, These sensors start giving issues after a while, and in the worst-case scenario, sensor replacement is the only way to mitigate them.
