Hydraulic Test

HYDRAULIC TEST

Measure the line pressure.

NOTE:
- Conduct the test at the normal operating temperature of the ATF: 50 - 80 °C (122 - 176 °F).
- The line pressure test should always be carried out in pairs. One technician should observe the conditions of the wheels or the wheel stoppers outside the vehicle while the other is conducting the test.
- Be careful to prevent the SST's hose from interfering with the exhaust pipe.

1. Warm up the ATF.
2. Remove the test plug on front left side of the transmission case front left side and connect the SST.
SST 09992-00095 (09992-0151, 09992-00271)

3. Fully apply the parking brake and chock the 4 wheels.
4. Start the engine and check the idle speed.
5. Keep your left foot depressing firmly the brake pedal and shift the shift lever into the D position.
6. Measure the line pressure while the engine is idling.
7. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when the engine speed reaches the specified stall speed (in the mechanical system tests).
8. In the same manner, conduct the test in the R position.




Specified line pressure (5VZ-FE)




Specified line pressure (2UZ-FE)

If the measured pressures are not up to the specified values, recheck the throttle cable adjustment and retest.
