What is DTC P0300?
P0300 indicates that two or more cylinders are experiencing misfires. A misfire occurs when an insufficient amount of fuel is burned in a cylinder. A misfire from two or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure.
What to do if the P0300 trouble code is still present?
If the P0300 trouble code is still present after the spark plugs, spark plug wires and/or coil packs have been replaced, they will inspect the fuel injectors and fuel injector system for faults Older vehicles have a distributor cap and rotor button system.
What’s the engine speed on a DTC P0300?
The engine speed is between 450 RPM and 3,001 RPM. The ignition voltage is between 11.0 volts and 16 .0 volts. The engine coolant temperature is between -7°C (19°F) and 130°C (266°F). Fuel level greater than 10%
Where is the crankshaft position sensor located on a DTC P0300?

What does DTC mean on OBD2 freeze frame?
This code means that the fuel injector present in bank 1 was in closed-loop mode when the error took place. There’s no fuel injector present in bank 2. The engine might be a 4 or 6 cylinder unit with only a single bank. This DTC refers to the air entering the motor below 100%. It denotes the engine coolant temperature.
If the P0300 trouble code is still present after the spark plugs, spark plug wires and/or coil packs have been replaced, they will inspect the fuel injectors and fuel injector system for faults Older vehicles have a distributor cap and rotor button system.
Can a freeze frame overwrite fuel trim data?
Made to identify emissions-related faults, freeze frame data could help you identify other problems as well. Only data associated with a misfire fault or fuel trim can overwrite the freeze frame data.
When to record freeze frame data in OBD2?
However, the system records freeze frame data only when it encounters a failure the first time or for two trips in a row. Here’s an overview of what the freeze frame interpretation chart looks like: This code means that the fuel injector present in bank 1 was in closed-loop mode when the error took place.
