Here we will discuss codes related to the ignition system which involves, but is not limited to the spark plugs, ignition coils, camshaft position sensors, and crankshaft position sensor. These systems are responsible for igniting the air/fuel mixture. Misfire codes are among the most common codes in this section which range from P0300 to P0312. These can oftentimes be fixed rather easily and inexpensively, but this section also includes more complicated systems such as camshaft and crankshaft timing. These systems can require advanced diagnostic equipment to properly diagnose, but we have some tips to help simplify these and make them a little easier to understand and repair.
