Line Pressure Test

This test measures line pressures as a means of checking the hydraulic components and inspecting for oil leakage.

Preparation
1. Perform the preparation procedure outlined in STALL TEST. Stall Test
2. Connect a tachometer to the engine.
3. Assemble the SST.

Procedure:

Procedure
1. Start the engine.
2. Check the idle speed and ignition timing in P range.

Idle speed: 680 - 720 rpm

Ignition timing (BTDC): 11 - 13 °
(TEN terminal of data link connector grounded)

3. Shift the selector lever to D range and read the line pressure at idle.
4. Connect the SST (49 0378 400A) to the line pressure inspection port.

CAUTION: Steps 4 and 5 must be performed within five (5) seconds to prevent possible transmission damage.

5. Depress the brake pedal firmly with the left foot and gradually depress the accelerator pedal with the right foot.
6. Read the line pressure as soon as the engine speed becomes constant, then release the accelerator pedal.

CAUTION: Idle for at least one (1) minute to cool the ATF and to prevent Its deterioration.

7. Shift the selector lever to N range and run the engine at idle for at least one (1) minute.
8. Read the line pressure at idle and at the engine stall speed for each range in the same manner.

Specified Line Pressure:

Specified line pressure:

9. Install a new square head plug in the inspection port.

Tightening torque: 4.9 - 9.8 N.m (50 - 100 kgf.cm, 43 - 87 in.lbf)
