The stall speed test is used to check the overall performance of the transaxle and engine by measuring the maximum engine speeds in the forward and reverse ranges.

Notice: This test should always be performed at a normal operating fluid temperature of 70 to 80°C (158 to 176°F). DO NOT run engine at stall speed for more than five seconds continuously. If this precaution is not observed, engine oil and transaxle fluid temperatures may rise excessively high.

1. Connect the scan tool to the Data Link Connector (DLC) and display the engine RPM.
2. Apply the parking brake and block the vehicle wheels.
3. Turn the ignition switch to the ON position.
4. Press the brake pedal fully.
5. Ensure that the manual selector lever is in the park (P) range.
6. Start the engine.
7. Move the manual selector lever to the drive (D) range.
8. Press the accelerator pedal fully at Wide Open Throttle (WOT). While watching the scan tool, quickly read and record the engine speed (RPM) once it becomes constant/stall speed.
9. Release the accelerator pedal immediately after the stall speed is recorded.
10. Using the same method, record the stall speed in Second 2, Low L, and Reverse (R) ranges.
11. Return the selector lever to park (P) range and turn the ignition switch to LOCK.

Evaluation

The stall speed should fall within 2,000 to 2,500 RPM in all tested gear ranges. Refer to the Stall Speed Test Diagnosis for causes of higher or lower stall speed.
