Stall Speed Test Procedure

WARNING: This page is about a different car, the 2002 Toyota ECHO, 2002 Toyota Celica, 2001 Toyota ECHO, and 2001 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.
  1. Testing is done to check overall performance of transaxle and engine by measuring maximum engine speeds in Drive and Reverse.
  2. Block front and rear wheels. Connect scan tool to Data Link Connector (DLC3) to monitor engine RPM. Apply parking and service brakes. Start engine. Shift transaxle into Drive. Fully depress accelerator pedal. Release pedal within 10 seconds.
  3. Record highest engine RPM. Compare reading obtained to specification. Stall speed should be 2220-2520 RPM for Celica and 2130-2550 RPM for ECHO. Repeat test in Reverse.
  4. If stall speed is same for both positions, but lower than specified RPM, engine output may be insufficient or stator one-way clutch is not operating properly.
    NOTE: If stall speed RPM is more than 600 RPM less than specification, torque converter may be faulty.
  5. If stall speed in Drive is higher than specifications, forward clutch may be slipping, No. 2 one-way clutch may not be operating properly, or line pressure is too low.
  6. If stall speed in Reverse is higher than specifications, reverse clutch may be slipping, 1st/reverse brake may be slipping or line pressure is too low.
  7. If stall speed in Reverse and Drive is higher than specifications, line pressure is too low, incorrect fluid level exists or No. 2 one-way clutch is not operating properly.
