Fuel Injection Pump Top Dead Center Offset Adjustment: Notes
This procedure should only be used when a Diagnostic Trouble Code (DTC) has directed you to do so, or one of the following repairs has been performed:
- A DTC P1214 is set.
- The engine has been replaced.
- The front engine cover has been replaced.
- The Powertrain Control Module (PCM) and the injection pump have been replaced at the same time.
- The crankshaft position sensor has been replaced.
The PCM has the ability to perform a Top Dead Center (TDC) Offset Learn when one is not present or has been cleared. This procedure allows the PCM to be updated with the correct TDC offset for the vehicle.
The TDC Offset specification is only to be used after the Learn procedure has been performed.
