DTC P0300-P0306: Engine Misfire Detected: Description

Powertrain Control Module (PCM) uses information from Ignition Control (IC) module and Camshaft Position (CMP) sensor in order to determine when an engine misfire is occurring. By monitoring variations in crankshaft rotation speed for each cylinder, PCM is able to detect individual misfire events. A misfire rate that is high enough can cause 3-way catalytic converter to overheat under certain conditions. Malfunction Indicator Lamp (MIL) will flash on and off when conditions for 3-way catalytic converter overheating are present.
