Theory of Operation
The Governor Pressure Control System is used to regulate the governor pressure which controls the shifts for first,
second, and third gear. The Governor Pressure Control System test verifies that the requested pressure and the
actual pressure are within a predetermined tolerance.
When Monitored:
While the engine is running and the gear selector is in the Drive position.
Set Condition:
This DTC will set if the monitored Governor Pressure is greater than 41.4 kPa(6psi)for5secondswhilethe
gear selector is in the Drive position with the road speed equal to zero - sixtimes during a drive cycle. The
transmission oil temperature must be between 23 - 88° C (73 - 190° F).
