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 a random cylinder misfire code?
Vacuum leaks on individual cylinders commonly occur around intake port gaskets or vacuum hose connections. Insufficient valve lash , a broken piston ring or a leaking cylinder head gasket can cause a partial loss of compression. Depending on where the vacuum leak is on the manifold, it can generate random or specific cylinder misfire codes.
What is likely cause of a code P0300?
The P0300 error code can have many different root causes, but the most common cause is in the ignition system. The ignition system provides a spark to the cylinder that allows the gasoline to combust under pressure. As the ignition system ages, the delivery of spark to the combustion chamber can degrade.
