P0300-00 Engine Misfire Detected Causes_58 Auto The P0300 trouble code indicates that the engine has detected multi-cylinder misfire. The fault systems that cause this phenomenon include the fuel injection system and ignition system, which are basically electrical circuit and electronic control faults. Here are the relevant explanations: ECU: The Powertrain Control Module (ECU) can detect "misfire" by monitoring the 3X reference voltage of the Ignition Control (IC) module and the camshaft position input signal from the camshaft position sensor. Fuel Injection System: The fuel injection system refers to a fuel supply device that injects a certain amount of fuel directly into the cylinder or intake manifold under certain pressure using an injector. Depending on the type of fuel injected, it can be classified into gasoline injection systems, diesel injection systems, gas fuel injection systems, etc.
