What is a Car Sensor?

Car sensors are electronic gadgets that continuously collect data about the internal and external conditions of your car, acting as its eyes and ears. These small, frequently unseen technical marvels whisper secrets to your car’s brain (the ECU) to keep everything operating securely and smoothly by converting physical and chemical changes into electrical impulses.

Common Types of Car Sensors

Sensors form the backbone of modern automotive technology. From monitoring air-fuel ratios to safeguarding against wheel lock during braking, the below list of sensors is widely used.

1. Oxygen Sensor (O2 Sensor)

They keep an eye on the amount of oxygen in automobile exhaust systems. The Engine Control Unit receives this information. With the feedback, it adjusts the air/fuel mixture. The oxygen sensor in the car ensures that the engine runs efficiently.

1. Manifold Absolute Pressure (MAP) Sensor

The main function of the MAP sensor is to transmit vital pressure information to the engine manifold. Unlike the intake airflow sensor, the MAP sensor uses indirect sensing to determine the intake air volume.

1. Mass Air Flow (MAF) Sensor

It gauges the amount of air entering the vehicle. This information is used to calculate how much fuel needs to be injected for the best possible combustion.

1. Throttle Position Sensor (TPS)

This is used to gauge the angle of the throttle flap located on the throttle body. This prevents a sticky throttle from dumping a ton of fuel into the engine if there is a problem between the pedal and the throttle.

1. ABS Wheel Speed Sensor

The wheel speed sensor in the ABS records the wheel’s rotational speed and sends the information to the ABS computer. During an emergency stop, the ABS computer uses the data from the ABS sensor to prevent the brakes from locking.

1. Coolant Level Sensor

Your car will overheat if there is not enough coolant in it. Because of this, the majority of cars have a coolant level sensor. These sensors prevent any coolant issues while you drive.

1. Transmission Speed Sensor

The transmission speed sensor uses the output shaft’s rotation to calculate road speed. For exact operation, it cooperates with wheel speed sensors.

1. Crankshaft Position Sensor

A multipurpose part that tracks different engine parameters. These include setting the ignition timing, detecting engine RPM, and evaluating engine speed. This sensor removes the need for manual distributor timing by doing these tasks.
