20 Types of Car Sensors and Their Functions

Car sensors are advanced technology features in the automotive field embedded by car manufacturers. The purpose of embedding sensors in cars is to send information to determine whether the car is still safe or has problems.

In addition, car sensors are useful for attracting a larger market share in the modern era as it is today. The following will explain the various types of car sensors along with their functions.

Types of Car Sensors and Their Functions

Here are various car sensors that you need to know along with their functions.

1. Intake Air Temperature Sensor (IAT)

The intake air temperature sensor functions to regulate the air temperature inside the intake manifold. You can find this sensor next to the air filter.

2. Mass Air Flow Pressure Sensor (MAF)

This sensor is also known as the AFM (Air Flow Meter) sensor and functions to measure the mass of air flowing to the intake manifold.

3. Throttle Position Sensor (TPS)

This sensor is commonly used in EFI cars and functions as a measure of the opening angle of the throttle valve. Additionally, data from this sensor can serve as a determinant of the fuel capacity to be injected into the engine.

4. Manifold Air Pressure Sensor (MAP)

This sensor functions to send information to the power control module to control and measure engine load.

5. Crankshaft Position Sensor (CKPs)

This sensor functions to measure how fast the car's RPM is.

6. Camshaft Position Sensor (Mps)

This sensor functions to identify the position of the cylinder whether it is in the correct position (top position) or not.

7. Fuel Tank Pressure Sensor

Its function is to measure the fuel pressure inside the car's tank.

8. Fuel Rail Pressure Sensor

Its function is to identify the fuel pressure in diesel engine vehicles.

9. Fuel Level Sensor

Its function is to measure the fuel capacity in the car's tank.

10. Fuel Temperature Sensor

This sensor functions to measure the temperature of the fuel flowing through the fuel line.

11. Fuel Line Pressure Sensor

This sensor functions to stabilize fuel pressure so that the fuel pump operates more optimally.

12. Air Fuel Ratio Sensor

This sensor functions to identify the air and fuel mixture in the tank, whether its composition is appropriate when the car engine is idling.

13. Knock Sensor

This sensor functions to identify detonation or engine knocking (a condition where the combustion process is not timely, causing explosions and making combustion inefficient).

14. Oil Pressure Sensor

This sensor functions as a detector of oil pressure in the car engine. If the oil pressure decreases, the oil indicator will light up. However, if the oil pressure drops too low, the car engine will automatically shut down.

15. Oxygen Sensor

This sensor functions to determine the amount of emissions that will be released by the engine.

16. Water Temperature Sensor (WTS)

Its function is to measure the coolant temperature so that the car does not easily overheat.

17. Refrigerant Pressure Sensor

This sensor functions as a controller for the air conditioning system.

18. Vehicle Speed Sensor (VSS)

Its function is to detect the speed of the car by identifying the number of wheel rotations.

19. Brake Pedal Sensor

This sensor functions to identify whether the brake position is being released or pressed.

20. Turbo Boost Sensor

This sensor functions to measure the air pressure provided by the turbocharger so that the pressure remains stable.

Hopefully, the review above adds to your knowledge. If your car has a malfunction in one of its sensors, you can take it to an official Daihatsu workshop for proper handling.
