WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.

CHECK TO SEE IF DTC P0890 IS PRESENT
1. With the scan tool, read Transmission DTCs.
  Is the status Active for this DTC or is the Starts Since Set counter set at 0?
  
  Yes
  - Go To 2
  No
  - Go To 5

1. Turn the ignition off to the lock position.
2. Disconnect the PCM C1 harness connector.
3. Disconnect the Transmission Solenoid/Pressure Switch Assembly harness connector.
4. Ignition on, engine not running.
5. With the scan tool in the TIPM, actuate the Transmission.
6. Measure the voltage of the (T9) OD Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T9) OD Pressure Signal circuit for a short to voltage.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 3
(T47) 2/4 PRESSURE SIGNAL CIRCUIT SHORTED TO VOLTAGE

NOTE:
Under TIPM, continue to actuate the Transmission.
1. Measure the voltage of the (T47) 2/4 Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T47) 2/4 Pressure Signal circuit for a short to voltage.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Go To 4
(T50) L/R PRESSURE SIGNAL CIRCUIT SHORTED TO VOLTAGE

NOTE:
Under TIPM, continue to actuate the Transmission.
1. Measure the voltage of the (T50) L/R Pressure Signal circuit.
  Is the voltage above 0.5 of a volt?
  
  Yes
  - Repair the (T50) L/R Pressure Signal circuit for a short to voltage.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals 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 in accordance with the Service Information. With the scan tool, perform Quick Learn.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
CHECK THE WIRING AND CONNECTORS
1. The conditions necessary to set the 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 wiring and connectors while checking for shorted and open circuits.
4. With the scan tool, check the Event Data to help identify the conditions in which the DTC was set.
  Were there any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the 40/41TE VERIFICATION TEST. Refer to 40/41TE TRANSMISSION VERIFICATION TEST .
  No
  - Test Complete.
