Line Pressure Tests

LINE PRESSURE TEST
This test measures line pressures for checking the hydraulic components and inspecting for oil leakage.

Preparation
1. Perform the preparation procedure:

- Check the engine coolant, engine oil, and ATF levels before testing.
- Warm the engine thoroughly to raise the ATF temperature to operating level (60-70 °C, 140-158°F)

2. Connect a tachometer to the engine.
3. Connect the SST to the line pressure inspection port (square head plug "L").





1. Start the engine and check the idle speed in P range.

Idle speed: 750 +/- 25 rpm

2. Shift the selector lever to D range and read the line pressure at idle for each range.
3. Connect the SST to the line pressure inspection port.

Caution: Step 4 - 5 must be performed within 5 seconds to prevent possible transaxle damage.

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

Caution: Idling for at least one minute is to cool the ATF and to prevent deterioration of the fluid.

6. Shift the selector lever to N range and run the engine at idle for at least one minute.
