What is the cause of a p0302 misfire detected code?
A misfire is just what it sounds like; a cylinder that is not firing as it should. The P0302 code is caused by a misfire on the number two cylinder. The Misfire monitor diagnostic is based on variation in crankshaft velocity. The PCM determines this information using the crankshaft position sensor and camshaft position sensor.
What causes random cylinder misfire?
If you lose a spark, whether from lack of coil voltage or any other reason, this can also lead to a cylinder misfire. If your fuel/air mix isn’t well balanced, meaning that too much or too little air is getting into the engine, you might see the same result.
How is a cylinder misfire detected?
The Engine Control Module (ECM) uses information from the crankshaft position sensor and the camshaft position sensor to determine when an engine cylinder misfire is occurring. By monitoring variations in the crankshaft rotation speed for each cylinder, the ECM can detect individual cylinder misfire events.
