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. Ensure gearshift lever is in Park. Start engine. Ensure transaxle is at normal operating temperature. Place gearshift lever in "R" position. Using scan tool, monitor pressure switch states. If any pressure switches close, go to next step. If any pressure switches do not close, go to step  3.
  2. Conditions necessary to set DTC are not present at this time. Test drive vehicle and allow transaxle to shift through all gears and ranges. Determine if delayed engagement or a no-drive symptom has occurred. If symptoms have occurred, go to next step. If symptoms have not occurred, using wiring diagram as a guide, inspect wiring and connectors associated with circuits in question. See WIRING DIAGRAMS . Wiggle wires while checking for shorted and open circuits. Repair as necessary. If circuits are okay, testing is complete.
  3. Ensure transaxle is at normal operating temperature. Check transmission fluid level. See appropriate SERVICING article in AUTOMATIC TRANSMISSIONS. Fill if necessary, and repair cause of low fluid level. If fluid level is okay, go to next step.
  4. Using scan tool, perform SHIFT LEVER POSITION test. If shift lever position test passed, go to next step. If shift lever position test did not pass, see DTC P0706: CHECK SHIFTER SIGNAL .
  5. Remove transaxle oil pan and primary oil filter. Check for excessive debris in oil pan or a plugged filter. Repair as necessary. If no problems are found, refill transaxle and go to next step.
  6. If no other potential causes for DTC P0944 remain, oil pump is assumed to be defective. Repair or replace as necessary. See appropriate OVERHAUL article.
