Fault code: P 12 17
English: The fuel injector circuit is short-circuited to the positive pole of No.5 cylinder.
Fuel injector circuit short to+-cylinder 5
Category: power system
Detailed meaning: The function of fuel injector is to atomize fuel to meet the requirements of combustion. The working principle is that when the electromagnetic coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is ejected at high speed through the annular gap between the shaft needle and the nozzle hole at the head of the needle valve, forming a mist. The electronic control unit controls the fuel injection amount by controlling the opening time interval of the fuel injector.
