Theory of Operation
The Governor Pressure Sensor is used by the PCM to adjust the Governor Pressure to a desired level for shifts in
first, second, and third gear. If the PCM detects the monitored sense voltage is greater than or less than a prede-
termined specification, the PCM 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.

Theory of Operation
The Transmission Control Output supplies power to the TCC, Overdrive, andGovernor Pressure Solenoids when in
normal operating mode. The Transmission Control Output Control circuit is constantly monitored by the PCM. If the
expected state of the Transmission Control Output Control circuit is different then the expected state, a correspond-
ing DTC will set and the PCM will de-energize the Transmission Control Output and place the transmission in Limp-
in.
When Monitored:
Continuously with the Ignition on.
Set Condition:
This DTC will set if the PCM monitored voltage of the Transmission Control Output Control circuit is different
than the expected voltage for the period 3.0 seconds.
