What is the ecv fuse?

The ECV fuse, or Electric Control Valve fuse, is a safety component in automotive electrical systems that protects the circuit controlling the electric control valve, which regulates various functions such as airflow or fuel injection. If the fuse blows, it interrupts the circuit, preventing damage to the control valve and associated components. This fuse ensures reliable operation of the vehicle’s systems and prevents electrical overloads. If a vehicle experiences issues related to the electric control valve, checking the ECV fuse is often a recommended troubleshooting step.
