Applicable models: All car manufacturers
Chinese meaning explanation: Ignition coil F main control circuit is low
English meaning: Ignition Coil F Primary Control Circuit Low
P2315 fault code related knowledge:
The function of the ignition coil is to convert the 12 volts of the car battery into the thousands or even tens of thousands of volts needed for the spark plug to ignite. There are two sets of coils in the ignition coil, the primary coil and the secondary coil. The primary coil has thicker enameled wire with fewer turns; the secondary coil uses thinner enameled wire with relatively more turns. When the primary coil is powered on, a strong magnetic field is generated around as the current increases, and the iron core stores the magnetic field energy; when the switching device disconnects the primary coil circuit, the magnetic field of the primary coil decays rapidly, and the secondary coil will induce high voltage
