What is the resistance value of EFI automobile nozzle under normal circumstances?

Nozzle can be divided into two types according to the resistance of electromagnetic coil: low resistance nozzle and high resistance nozzle. In general, the resistance of low-resistance nozzle is about 2-3 Ω, and that of high-resistance nozzle is about13-16 Ω. The shape of the electric plug of the oil nozzle is often used to indicate the type of the oil nozzle and the resistance value.

The fault of the electromagnetic coil of the fuel injector can be judged by detecting the resistance value. Infinite resistance indicates that the coil is open, too low resistance indicates short circuit, and the resistance value is much higher than the specified value, indicating that the coil is aging.
