Turn the ignition off.
WARNING: The fuel system is under a constant pressure even with the
engine off. Before testing or servicing any fuel system hose,fitting or line,
the fuel system pressure must be released.
Remove the Fuel Pump Module and inspect the Fuel Inlet Strainer.
Is the Fuel Inlet Strainer plugged?
All
Yes
→
Replace the Fuel Pump Inlet Strainer.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No

Symptom:
P0711-TRANS TEMP SENSOR, NO TEMP RISE AFTER START
When Monitored and Set Condition:
P0711-TRANS TEMP SENSOR, NO TEMP RISE AFTER START
When Monitored:
Continuously with the key on and the engine running.
Set Condition:
After 2 trips in which the trans sump temp is < 5°C (40° F) and does not
rise more than 8°C (16° F) after 20 minutes of run time with Veh Spd > 48 kmh (30 MPH).
It will also set if the eng temp is < 38°C (100° F) with trans temp > 127°C (260° F).

Turn the ignition on.
Note: To test the transmission temperature sensor, the engine and trans-
mission temperature must be at or below 29.4°C (85° F).
With the DRBIII
t read:
Engine Coolant temperature and record.
Transmission temperature and record.
Is the transmission temperature within 5°C (9°F) of the engine coolant temperature?

Note: To test the transmission temperature sensor, the engine and trans-
mission temperature must be at or below 29.4°C (85° F).
Start the engine and let it idle in Drive with parking brake on, while monitoring the
Transmission Temperature Sensor with the DRBIII
t.
Look for the temperature to rise 8°C (15°F) within a ten minute period.
Did the trans temperature increase at a steady rate and rise 8°C (15°F) over a 10
minute period?
All
Yes
→
No

Turn ignition off.
Remove the Transmission pan.
Disconnect the Governor Pressure Sensor/Transmission Temperature Sensor connec-
tor.
Note: Check connectors - Clean/repair as necessary
Measure the resistance of the Transmission Temperature Sensor.
Note: Acceptable Sensor Resistance Ranges in OHMS
Sensor Temperature Minimum Maximum
-40°C (-40°F) 1094 1176
0°C (32°F) 1587 1672
25°C (77°F) 1960 2040
70°C (158°F) 2709 2860
100°C (212°F) 3284 3500
120°C (120°F) 3684 3950
150°C (302°F) 4110 4450
Is the resistance within the specified range when the sensor is at the given
temperature?
All
Yes
→
Test Complete.
No
→
Replace the Governor Pressure/Transmission Temperature Sen-
sor in accordance with the Service Information.
Perform TRANSMISSION VERIFICATION TEST VER - 1.

At this time, the conditions required to set the DTC are not present.
Note: Use the Freeze Frame Data to help duplicate the conditions that set
the DTC. Pay particular attention to the DTC set conditions, such as, VSS,
MAP, ECT, and Load.
Note: Visually inspect the related wiring harness. Look for any chafed,
pierced, pinched, or partially broken wires.
Note: Visually inspect the related wiring harness connectors. Look for
broken, bent, pushed out, or corroded terminals.
NOTE: Refer to any Technical Service Bulletins that may apply.
Were any problems found?
