P1214
CIRCUIT DESCRIPTIONThe Powertrain Control Module (PCM) has the ability to determine the amount of offset needed to bring the engine to Top Dead Center (TDC). This is used by the PCM to determine proper injection time.
CONDITIONS FOR RUNNING THE DTC
The ignition is in the ON position.
CONDITIONS FOR SETTING THE DTC
^ TDC offset more than 2.46 degrees
or
^ TDC Offset less than -2.46 degrees
ACTION TAKEN WHEN THE DTC SETS
^ The control module illuminates the Malfunction Indicator Lamp (MIL) on the second consecutive ignition cycle that the diagnostic runs and fails.
^ The control module records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the control module stores this information in the Failure Records. If the diagnostic reports a failure on the second consecutive ignition cycle, the control module records the operating conditions at the time of the failure. The control module writes the operating conditions to the Freeze Frame and updates the Failure Records.
CONDITIONS FOR CLEARING THE DTC
^ A current DTC Last Test Failed clears when the diagnostic runs and passes.
^ A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
^ Use a scan tool in order to clear the DTC.
DIAGNOSTIC AIDS
The PCM will only run the diagnostic test if the TDC offset adjustment time set procedure has been activated. The vehicle will most likely not be brought in with this DTC set. Refer to Fuel Injection Pump TDC Offset Adjustment.
