5.
CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE
Turn the ignition off to the lock position.
Disconnect the TCM C2 harness connector.
Ignition on, engine not running
Measure the voltage of the (T52) Output Speed Sensor Signal circuit.
Is the voltage above 0.2 volts?
Yes
>> Repair the (T52) Output Speed Sensor Signal circuit for a
short to voltage.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
No
>> Using the schematics as a guide, check the Transmission
Control Module (TCM) terminals for corrosion, damage, or
terminal push out. Pay particular attention to all power and
ground circuits. Check for any Service Bulletins for possible
causes that may apply. If no problems are found, replace
the TCM per the Service Information.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
6.
CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR AN OPEN (HIGH RESISTANCE)
Turn the ignition off to the lock position.
Disconnect the TCM C2 harness connector.
Connect a jumper wire between the (T52) Output Speed Sensor Signal
circuit and B(+) in the Output Speed Sensor harness connector.
Using a 12-volt test light connected to ground, check the (T52) Output
Speed Sensor Signal circuit in the TCM C2 harness connector.
NOTE: The test light must illuminate brightly. Compare the bright-
ness to that of a direct connection to the battery.
Does the test light illuminate brightly?
Yes
>> Go To 7
No
>> Repair the (T52) Output Speed Sensor Signal circuit for an
open or high resistance.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)

7.
CHECK THE (T130) OUTPUT SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE
Disconnect the jumper wire.
Disconnect the TCM C2 harness connector.
Measure the voltage of the (T130) Output Speed Sensor Ground circuit.
Is the volage above 0.2 volts?
Yes
>> Repair the (T130) Output Speed Sensor Ground circuit for a short to voltage
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)
No
>> Go To 8
8.
CHECK THE (T130) OUTPUT SPEED SENSOR GROUND CIRCUIT FOR AN OPEN (HIGH RESISTANCE)
Turn the ignition off to the lock position.
Disconnect the TCM C2 harness connector.
Connect a jumper wire between the (T130) Output Speed Sensor
Ground circuit in the Output Speed Sensor harness connector and B(+).
Using a 12-volt test light connected to ground, check the (T130) Output
Speed Sensor Ground circuit in the TCM C2 harness connector.
NOTE: The test light must illuminate brightly. Compare the bright-
ness to that of a direct connection to the battery.
Does the test light illuminate brightly?
Yes
>> Go To 9
No
>> Repair the (T130) Output Speed Sensor Ground circuit for
an open or high resistance.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS-
MISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
9.
CHECK THE OUTPUT SPEED SENSOR
Turn the ignition off to the lock position.
Remove the Output Speed Sensor per the Service Information.
Check the Output Speed Sensor for any debris buildup or damage.
Did the Output Speed Sensor show any signs of debris buildup or damage?
Yes
>> If there is a debris build up, clean the Output Speed Sensor as necessary and reinstall. If damaged or
questionable in condition, replace the Output Speed Sensor.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)

REPLACE SPEED SENSOR AND TEST DRIVE VEHICLE
Turn the ignition off to the lock position.
Replace the Output Speed Sensor per the Service Information
Reconnect all previously disconnected harness connectors.
Ignition on, engine not running
With the scan tool, erase all Transmission DTCs.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT - STANDARD
PROCEDURE)
NOTE: Test drive the vehicle to speeds that will allow Torque Converter lock-up.
With the scan tool, read Transmission DTCs.
Does the DTC P0721 reset?
Yes
>> Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion,
damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for any
Service Bulletins for possible causes that may apply. If no problems are found, replace the TCM per the
Service Information.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)
No
>> Test Complete.
11.
INTERMITTENT WIRING AND CONNECTORS
The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
Wiggle the wires while checking for shorted and open circuits.
Were there any problems found?
Yes
>> Repair as necessary.
Perform CVT VERIFICATION TEST. (Refer to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - CVT -
STANDARD PROCEDURE)
No
>> Test Complete.
