Stall Speed Test

NOTICE: 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 50 to 80° C (122 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. Install a scan tool and monitor engine speed (rpm).
2. Apply parking brake and block vehicle wheels.
3. Turn ignition switch to the ON position.
4. Press brake pedal fully.
5. Ensure that the manual selector is in the Park (P) position.
6. Start engine.
7. Move manual selector to Drive (D) position and press Overdrive switch.
8. Press accelerator pedal fully Wide Open Throttle (WOT). While watching scan tool, quickly read and record the engine speed (rpm) once it becomes constant (stall speed).
9. Release accelerator pedal immediately after stall speed is recorded.
10. Keeping the manual selector in Drive (D) position, release the Overdrive switch.
11. Using the same method described in Steps 8 and 9, record the stall speed in D, 2, L and R positions.
12. Return selector lever to Park (P) position and turn ignition switch to the LOCK position.





Evaluation
Stall speed should fall within 2400 to 2700 rpm in all tested gear positions. Refer to the STALL SPEED TEST DIAGNOSIS chart for causes of higher or lower stall speed.
