Volvo engine code DTC P02D1

Fuel Pressure, Timing and Quantity Threshold – Single Cylinder High Mass Flow This OBD monitor works by observing engine acceleration as measured by the crank angle sensor. This acceleration measurement is taken during a crank angle window where the current firing cylinder should be generating it’s torque. Acceleration is then filtered with a low pass filter and after all cylinders have fired, an average acceleration of all cylinders is generated. The error of each cylinder is calculated as the deviation of it’s individual acceleration reading from the average acceleration value. An average quantity offset value for all cylinders (either positive or negative) is calculated and if a single cylinder’s fuel value deviates from a calibrated limit a DTC is set.
