The fuel pump relay plays a vital role in the operation of your vehicle's fuel system. Here's how it works:
Turns the fuel pump on/off: The primary function of the fuel pump relay is to control the current flowing to the fuel pump.
Voltage regulation: The relay helps regulate the voltage supplied to the fuel pump. This ensures that the pump receives the correct voltage for efficient operation, which is critical to keeping fuel pressure within engine specifications.
In summary, the fuel pump relay is essential for controlling the operation of the fuel pump, ensuring it receives the correct voltage, protecting electrical components, and enabling efficient diagnostic functions in modern vehicles.
