Measure the resistance of the Transmission Temperature Sensor between the (T54) Transmission Temperature Sen-
sor Signal circuit and the (K900) Sensor Ground circuit.

Using the chart above, compare the Temperature Sensor temperature to the correlating resistance value.

Is the Temperature Sensor resistance above the maximum specification listed in the chart?

Yes

>> Replace the Governor Pressure/Transmission Temperature Sensor per the Service Information. (Refer to

CHECK THE POWERTRAIN CONTROL MODULE

Reconnect all disconnected connectors.

Ignition on, engine not running.

With the scan tool, erase Engine DTCs.

Turn the ignition off to the lock position.

Disconnect the Governor Pressure Sensor connector internal to the
transmission.

Connect a jumper wire between the (T54) Transmission Temperature
Sensor Signal circuit and the (K900) Sensor Ground circuit in the
Transmission Solenoid Assembly harness connector.

Ignition on, engine not running.

With the scan tool, read Engine DTCs.

Did the DTC Transmission Oil Temperature Sensor Voltage Too
Low set?

Yes

>> Go To 12

No

>> Using the schematics as a guide, check the Powertrain

Control Module (PCM) pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay
particular attention to all power and ground circuits. If no problems are found, replace and program the
PCM per the Service Information. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/
POWERTRAIN CONTROL MODULE - REMOVAL)

Perform RE TRANSMISSION VERIFICATION TEST VER - 1 (GAS). (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)

INTERMITTENT WIRING AND CONNECTORS

The conditions necessary to set this DTC are not present at this time.

Use the Freeze Frame Data to help duplicate the conditions in which the DTC originally set. Pay particular attention
to the DTC set conditions, such as, VSS, MAP, ECT, and Load

Using the schematics as a guide, visually inspect the related wiring harness. Look for any chafed, pierced, pinched,
or partially broken wires.

Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.

Wiggle the wiring and connectors while checking for any possible open or shorted circuits.

Check for any Service Information Tune-ups or Technical Service Bulletins that may apply.

Were there any problems found?

Yes

>> Repair as necessary.

Perform RE TRANSMISSION VERIFICATION TEST VER - 1 (GAS). (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 48RE - STANDARD PROCEDURE)

No

>> Test Complete.

•

When Monitored:
Continuously with the ignition on, engine running, and gear selector NOT in park or neutral.

•

Set Condition:
This DTC will set if the vehicle speed (reported from the CAB module) is above 24 Kmh (15 mph), and the
monitored Output Shaft Speed is below 60 RPM for 2.6 seconds.

Possible Causes

Diagnostic Test

1.

CHECK IF THE DTC IS CURRENT

Ignition on, engine not running.

With the scan tool, read Engine DTCs.

Record the Freeze Frame data for the reported DTC.

With the scan tool, erase DTCs.

Turn the ignition off to the lock position.

Using the Freeze Frame data recorded earlier, try to duplicate the conditions in which the DTC originally set.

NOTE: It may be necessary to road test the vehicle to duplicate the original set conditions.
With the scan tool, read Engine DTCs.

Did the DTC reset?

Yes

>> Go To 2

No

>> Go To 11

2.

CHECK IF A PARK/NEUTRAL DTC IS PRESENT

Is there a Park/Neutral DTC present?

Yes

>> Refer to the Transmission category and perform the appropriate symptom(s). (Refer to 21 - TRANS-

MISSION/TRANSAXLE/AUTOMATIC - 48RE - DIAGNOSIS AND TESTING)

No
