Theory of Operation
The Governor Pressure Solenoid is used to control governor pressure. Governor pressure is used to shift between
first, second, and third gear.
When Monitored:
Continuously with the ignition on.
Set Condition:
This DTC will set if the ECM monitored voltage detected on the Governor Pressure Solenoid Control circuit is
different than the expected voltage. Note: To clear this DTC, it is necessary to drive the vehicle at a sustained
speed which would allow the TCC and/or Overdrive Clutch to operate.

Theory of Operation
The Governor Pressure Sensor is used by the ECM to adjust the Governor Pressure to a desired level for shifts in
first, second, and third gear. If the ECM detects the monitored sense voltage is greater than or less than a prede-
termined specification, the ECM will set the desired DTC.
When Monitored:
Continuously with the ignition on and the engine running.
Set Condition:
This DTC will set when the monitored sense voltage from the Governor Pressure Sensor is above 4.89 volts
for the period of 8.5 seconds.
