Product introduction: 

Automotive oil pump control unit

The function of the fuel pump control module is to suck the fuel out of the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure to ensure continuous fuel supply to the fuel injectors. For example, the w221 fuel pump control module is next to the fuel pump.

The main device is the relay. As a kind of electrical control device, the relay needs to be connected in the circuit to form two control systems: the control system (also known as the input circuit) and the controlled system (also known as the output circuit). The electronic fuel pump control unit will regulate the power of the electric fuel pump so that the electric fuel pump can deliver exactly the required amount of fuel.

The oil pump control unit is directly proportional to the price of the car. If the car price exceeds 100,000 RMB, the oil pump control unit needs 500+ RMB; if the car price is 150,000 to 200,000 RMB, the oil pump control unit needs 8,900 RMB; if the car price exceeds 200,000 RMB, or it is a famous car, it needs 1,000+ RMB.

Fuel pump is a technical term in the auto parts industry. It is one of the basic components of the fuel injection system of EFI vehicles. It is located in the vehicle's fuel tank and operates the fuel pump when the engine is started and running. If the engine stops and the ignition switch is still turned on, the HFM-SFI control module turns off the fuel pump power supply to avoid accidental ignition; the function of the fuel pump is to suck fuel from the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish Certain fuel pressure.

The symptoms of a bad oil pump control module are:

1. Acceleration is weak, and there is a sense of frustration when rushing to refuel;

2. Bad startup;

3. There is a buzzing sound when driving;

4. The engine fault light is on;

5. Engine shaking.
