Diagnostic Test

WARNING: This page is about a different car, the 2012 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.

CHECK TO SEE IF THE DTC IS ACTIVE
1. With the scan tool, read Transmission DTCs.
  Is the status Active or is the Starts Since Set counter 2 or less for this DTC?
  
  Yes
  - Go To 2.
  No
  - Go To 9.
CHECK IF BOTH SPEED SENSORS SHOW NO SIGNAL
1. With the scan tool, read Transmission DTCs.
  Are both the Input and Output Speed Sensor No Signal DTCs set?
  
  Yes
  - Check the C106 connector for improper connection and repair as necessary.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  - If no problems are found in the C106 connector - Go To 3.
  No
  - Go To 3.
CHECK THE (T16) TRANSMISSION CONTROL OUTPUT CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Disconnect the Output Speed Sensor harness connector.
3. Ignition on, engine not running.
4. With the scan tool under TIPM, actuate the Transmission.
5. Using a 12-volt test light connected to ground, check the (T16) Transmission Control Output circuit at the Output Speed Sensor harness connector.
  NOTE:
  The test light must illuminate brightly. Compare the brightness to that of a direct connection to the battery.
  
  Does the test light illuminate brightly?
  
  Yes
  - Go To 4.
  No
  - Repair the (T16) Transmission Control Output circuit for an open or high resistance.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE

1. Turn the ignition off to the lock position.
2. Disconnect the TCM C2 harness connector.
3. Ignition on, engine not running.
4. Measure the voltage of the (T52) Output Speed Sensor Signal circuit.
  Is the voltage above 0.5 volts?
  
  Yes
  - Repair the (T52) Output Speed Sensor Signal circuit for a short to voltage.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  No
  - Go To 5.
CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR AN OPEN

1. Turn the ignition off to the lock position.
2. Measure the resistance of the (T52) Output Speed Sensor Signal circuit between the TCM C2 harness connector and the Output Speed Sensor harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go To 6.
  No
  - Repair the (T52) Output Speed Sensor Signal circuit for an open.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR A SHORT TO GROUND

1. Measure the resistance between ground and the (T52) Output Speed Sensor Signal circuit.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Repair the (T52) Output Speed Sensor Signal circuit for a short to ground.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  No
  - Go To 7.
CHECK THE (T130) OUTPUT SPEED SENSOR GROUND CIRCUIT FOR AN OPEN

Fig 5: Measuring Resistance Of Output Speed Sensor Ground Circuit

1. Measure the resistance of the (T130) Output Speed Sensor Ground circuit between the TCM C2 harness connector and the Output Speed Sensor harness connector.
  Is the resistance below 5.0 ohms?
  
  Yes
  - Go To 8.
  No
  - Repair the (T130) Output Speed Sensor Ground circuit for an open.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
CHECK THE OUTPUT SPEED SENSOR
1. Turn the ignition off to the lock position
2. Replace the Output Speed Sensor in accordance with the Service Information.
3. Reconnect all previously disconnected connectors.
4. Ignition on, engine not running.
5. With the scan tool, erase all Transmission DTCs.
6. Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  NOTE:
  Make sure to perform a test drive of the vehicle.
7. With the scan tool, read Transmission DTCs.
  Did the DTC P0722 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 in accordance with the Service Information.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  No
  - Repair is complete.
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.
3. Wiggle the wires while checking for shorted and open circuits.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Refer to STANDARD PROCEDURE and perform the CVT VERIFICATION TEST.
  No
  - Test Complete.
