Some misfire complaints are a flashing check engine light, and a P0300 to P0312 diagnostic trouble code (DTC) indicates that one or more cylinders are misfiring. The engine usually feels rough, lacks power and uses more fuel than usual. For example, if the engine is in open-loop operation, it might not run the misfire monitor.

This standardized many of the onboard emissions protocols and codes and allowed states to perform onboard emissions testing. As time passed, even large trucks and motorcycles adopted this same method to test the emissions status of a vehicle. These PIDs focus on the how the engine burns fuel and manages emissions.

Drivers might experience a rough-running engine, lack of power, or increased fuel consumption. Misfires also significantly increase hydrocarbon emissions, which can cause a vehicle to fail an emissions test. The post What different engine misfire codes mean appeared first on Tire Review Magazine.

Engine code P0442 stands for “Evaporative Emission Control System Leak Detected (Small Leak).” It’s a diagnostic trouble code indicating problems with the Evaporative Emission Control (EVAP) System. It prevents fuel vapor from escaping into the atmosphere via the fuel tank or fuel system and directs it to the engine to burn off.
