CIRCUIT DESCRIPTION
The PCM has the ability to determine the amount of offset needed to bring the engine to top dead center. This is used by the PCM to determine proper injection time.

CONDITIONS FOR SETTING THE DTC
TDC offset greater than 2.5 degrees.
OR
TDC Offset less than -2.5 degrees.

ACTION TAKEN WHEN THE DTC SETS
The Malfunction Indicator Lamp (MIL) will illuminate on 2 test failures.

CONDITIONS FOR CLEARING THE MIL/DTC
^ The PCM will turn the MIL off after three consecutive trips without a fault condition.
^ A History DTC will clear when forty consecutive warm-up cycles that the diagnostic does not fail (coolant temperature has risen 5°C (40°F) from start up coolant temperature and engine coolant temperature exceeds 71°C (160°F) that same ignition cycle.
^ Use of a Scan Tool.

DIAGNOSTIC AIDS
The PCM will only run the diagnostic test when a time set procedure has been activated. It is highly unlikely that the vehicle will be brought in with this DTC set. Refer to TDC Offset. Service and Repair
