DTC P0216: Injection Timing Control System: Description
Timing of combustion is accomplished by delivering a pulse of fuel into combustion chamber at a desired degree of cylinder travel. This desired degree (desired timing) defines current position of cylinder in relationship to top dead center. This test compares desired timing to measured timing when certain conditions are met. To retard injection timing, PCM extends stepper motor. To advance injection timing, PCM retracts stepper motor.
