To calculate the fuel supply and the ignition time, the PCM (Powertrain Control Module) is based on the position of the crankshaft of the camshaft and the engine RPM. If the PCM detects that there is a variation of the preset parameters in the position of the camshaft and the crankshaft, which translates as an engine ignition failure soon after the start and the DTC code P0316 OBD2 is established. This misfire is specific within 1,000 revolutions. It should be mentioned that other diagnostic codes related to misfiring may appear next to this diagnostic code.
