The low voltage side of the system is referred to as primary circuit. The ignition system converts battery voltage into the high voltage used to ignite the cylinder air/fuel mixture. What are the common causes of code P0301?Ī single cylinder misfire is typically caused by one of the following: That’s why with this code, a thorough diagnosis is mandatory. A P0301 code tells you only that a misfire has been detected, not WHY the cylinder is misfiring. A misfiring cylinder slows down momentarily, so by monitoring the cam and crank sensor signals, the PCM can calculate when a misfire occurs. The PCM determines this information using the crankshaft position sensor and camshaft position sensor. The P0301 code is caused by a misfire on the number one cylinder. The Misfire monitor diagnostic is based on variation in crankshaft velocity. We recommend Torque Pro What Does Code P0301 Mean?Ī misfire is just what it sounds like a cylinder that is not firing as it should.
