What Happens When the Fuel Pump Control Module Fails?
1 Answers
When the fuel pump controller fails, the vehicle will experience increased fuel consumption and black smoke from the exhaust pipe. The fuel pump, located at the bottom of the vehicle, is a device that draws fuel from the fuel tank, pressurizes it, and delivers it to the fuel supply line and the engine combustion chamber. It works in conjunction with the fuel pressure regulator to generate a certain fuel pressure and is one of the basic components of the fuel injection system in electronically controlled vehicles. Below is relevant information: 1. Structural Characteristics of the Fuel Pump: The fuel pump consists of an electric motor, a pressure limiter, and a check valve. The electric motor actually operates within the fuel inside the pump housing, where the fuel lubricates and cools the motor. Since there is nothing inside the housing that can ignite, there is generally no danger. The check valve is installed at the fuel outlet, and the pressure limiter is located on the pressure side of the pump housing, with a channel leading to the fuel inlet. 2. Precautions for Fuel Pump Inspection: When inspecting the fuel pump, the engine and other electronic components must not be in operation, as this can affect the voltage applied to the fuel pump and the current readings, compromising the inspection results.
