Test Description

The numbers below refer to the step numbers in the diagnostic procedures.

1. 2
   
   This step determines if DTC P0216 is a hard failure or an intermittent.
2. 4
   
   This step checks for an open or a short in the injection timing coil circuit 1.
3. 5
   
   This step checks for an open or short in the injection timing coil circuit 2.
4. 6
   
   The important thing in this step is that the PCM is sending a varying voltage. The voltage may vary between 1-12 volts and will usually vary between 5-6 volts when the engine is idling. This indicates that the PCM is okay and that there is a condition with the injection timing stepper motor. If there is a steady voltage present on any circuit, this indicates a condition with the PCM or a circuit that is shorted to voltage.
