Dfsk k07 cold car fire fault code p0300

Fault code: P0300 Chinese definition: Random/multi-cylinder detected misfire background knowledge: Cylinder misfire refers to the phenomenon that the mixture can't burn normally in the cylinder due to various reasons during engine operation. If the electronic control unit (ECU) detects a fire that may damage the catalytic converter, the fault indicator will flash and the engine should be shut down immediately. This fault code indicates that multiple cylinders are on fire, or the electronic control unit (ECU) cannot determine which cylinder is on fire. The failure causes include cylinder mechanical failure, fuel metering error, too high or too low fuel pressure, evaporative emission system failure, EGR valve stuck in open position, vacuum leakage of PCV system, ignition system failure, air flow meter failure and low oil level in fuel tank.
