14. When the engine speed no longer increases, quickly read the line pressure and release the accelerator
pedal.
15. Shift the selector lever to the N position and idle the engine for 1 min or more to cool the ATF.
16. Verify that the line pressure and LPS PID current values change according to the following graph by
changing the shift throttle opening angle when shifting to the D range and R position with the engine
running.
The line pressure standard other than when the engine is idling cannot be determined because the
maximum line pressure for this automatic transaxle is controlled by vehicle conditions.
