What does trouble code p0301 cylinder 1 misfire mean?

P0301 – Cylinder 1 Misfire Detected. The engine computer or PCM can detect a misfiring cylinder by monitoring the engine speed. Once misfire is detected, the PCM sets the trouble code and turns on the Check Engine light to alert the driver. The OBDII trouble code P0301 means that the cylinder number 1 misfires.

Can a bad crankshaft sensor cause a cylinder to misfire?

Should you feel or hear a brief stutter in the engine, it may be a sign of misfiring cylinders from a bad crankshaft position sensor. A failing crankshaft position sensor cannot provide the right information about piston positioning in the engine, causing a cylinder to misfire.

How does a head gasket cause an engine misfire?

Step 20 – A head gasket is used to seal the cylinder head to the engine block. The cylinder head is fastened to the engine block using head bolts that are tightened to a specific torque. When a head gasket wears (blows) it can allow coolant or exhaust gasses to enter the combustion chamber causing a cylinder misfire.
