Line Pressure Test

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

Preparation
1. Perform preparation procedure outlined in Stall Test.
2. Remove splash shield under front left bumper.





3. Connect SST (OK201 190 AAO/K94A-4214-AT) to line pressure inspection port (square-head "L" plug). It may be necessary to raise car to get at inspection port.

Procedure





1. Start engine.
2. Check idle speed in P range.
Idle speed: 750 - 850 rpm (with parking brake applied)
3. Shift selector lever to D range and read line pressure at idle.

Caution: Perform steps 4 and 5 within five seconds to prevent possible transaxle damage.

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

Notice: Idling for at least one minute cools ATF and prevents deterioration.

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





Specified line pressure

8. Install a new square-head "L" plug in inspection port.
Tightening torque: 44 - 86 inch lbs. (5.0 - 9.8 Nm, 51 - 100 kg.cm)
