DTC P0216: Injection Timing Control System: Description
The timing of the combustion event is accomplished by controlling the beginning of injection measured in degrees of crankshaft rotation before Top Dead Center (TDC). This test compares the desired timing to the measured timing when certain conditions have been met. In order to retard the injection timing, the Powertrain Control Module (PCM) extends the stepper motor. In order to advance the injection timing, the PCM retracts the stepper motor.
