Vehicles are the most common transportation facilities in our lives. They are very important to us. The ECU controls many functions in the engine. Sensors and the ECU work together to keep the vehicle in the optimum working state. New drivers may not know much about engine sensors. Let's take a look.

The automotive engine usually converts chemical energy into mechanical energy. The device is the heart of the car. Maintenance is essential. The engine works on the same principle as a human being. The computer ( brain ) sends out commands to control the execution of other parts ( body ). There are many feedbacks transmitted to the computer. The computer analyses and sends out commands. This cyclic process maintains the normal operation of the car.

Sensors are the input devices of the car computer. They transform various information, such as the car speed, temperature, engine operating conditions, into electrical signals. The computer receives and analyzes them. This process ensures that the vehicle is in the best working state.

Anyone who drives a car knows that while you are on the road, a whole bunch of dazzling warning lights pop up on the dashboard. And the icons of these indicators are vital for judging the working condition of the car. Many people, especially new drivers, don't quite understand what these icons mean. Here's a guide. Let's take a look!

The manifold absolute pressure sensor (MAP sensor) is the main component of the D-type fuel injection system in the engine. The sensor's role is equivalent to the air flow meter, which mainly measures how much air enters the engine. It sends the message to the engine control computer. This message is the basis of controlling the amount of fuel injection and ignition advance angle.

Engine knocking occurs due to many factors, such as too far advanced ignition time, the engine load, temperature and bad quality of fuel. When this phenomenon of detonation happens, gas combustion goes on before the piston moves to the top dead center. It makes noise and reduces the power of the engine. Furthermore, it damages the mechanical components. You want to avoid these accidents. The knock sensor is an essential component.

Suppose an improperly idling engine runs with weak acceleration, increased fuel consumption, excessive exhaust and other faults. There are no other faults in the fuel supply and ignition system. In that case, it is most likely that the oxygen sensor has problems. How should we test the faulty component? Let's dive right in.

The mass air flow (MAF) sensor is the sensor that determines the air flow into the engine. To obtain the optimum mixture concentration under all operating conditions, the sensor determines the amount of air drawn into the engine at each moment. The amount is the primary basis for the ECU's calculation (control) of the fuel injection.
