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 (6 psi) for 5 seconds while the gear selector is in the Drive position with the road speed equal to zero - six times during a drive cycle. The transmission oil temperature must be between 23 - 88° C (73 - 190° F).

Possible Causes
OTHER TRANSMISSION DTC'S PRESENT
5 VOLT SUPPLY CIRCUIT OPEN
5 VOLT SUPPLY CIRCUIT OPEN INSIDE THE TRANSMISSION
TRANSMISSION OIL BURNT OR OIL PAN HAS EXCESSIVE DEBRIS - INTERNAL TRANSMISSION DAMAGE
GOVERNOR PRESSURE SENSOR
GOVERNOR PRESSURE SOLENOID
VALVE BODY
ENGINE CONTROL MODULE 5 VOLT SUPPLY
