Diagnostic Procedure

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using scan tool, check for other transaxle-related DTCs. If DTCs P0715, P0720, P0867, P0944 or P1794 are also present, diagnose these DTCs first starting with P0944. If no other transaxle-related DTCs are present, go to next step.
  2. Using scan tool, perform 2ND GEAR CLUTCH test. Increase throttle angle or TP sensor degrees to 30 degrees for no more than a few seconds. Do not overheat transaxle. If test passes (input speed remains at zero), go to next step. If test does not pass, go to step  4.
  3. Conditions necessary to set DTC are not present at this time. Check shift linkage adjustment and adjust if necessary. See ADJUSTMENTS in appropriate SERVICING article in AUTOMATIC TRANSMISSIONS. Intermittent gear ratio DTCs can be set by problems with input and output speed sensor circuits. Using wiring diagram as a guide, inspect wiring and connectors associated with circuits in question. See WIRING DIAGRAMS . Remove starter relay from power distribution center. See Figure. Install Transmission Simulator (8333). Perform wiggle test using transmission simulator. Repair as necessary. Gear ratio DTCs can also be set under extreme temperature conditions. This is usually caused by an internal transaxle problem. Ask customer if problem is only experienced under extreme hot or cold conditions. Repair as necessary.
  4. Using scan tool, check for other transaxle-related DTCs. If DTC P0845 and/or P0846 are also present, solenoid assembly is assumed to be faulty. Repair or replace as necessary. See REMOVAL & INSTALLATION in appropriate SERVICING article in AUTOMATIC TRANSMISSIONS. If no other transaxle-related DTCs are present, go to next step.
    5. NOTE: Consult manufacturer's warranty documentation (if applicable) prior to performing repairs.
  5. Repair transaxle as necessary. See appropriate OVERHAUL article. If transaxle repair is necessary, check all components related to underdrive clutch and 2-4 clutch. Inspect oil pump and repair as necessary.
