Line Pressure Test
Line Pressure Test1. Perform mechanical system test preparation. (See Mechanical System Test Preparation.) Mechanical System Test
Warning:
^ Removing the square head plug when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the square head plug, allow the ATF to cool.
2. Connect the SSTs (49 0378 400C) to the line pressure inspection port and replace the gauge of the SST (49 0378 400C) with the SST (49 B019 901B).
3. Start the engine and warm it up until the ATF reaches 60-70°C (140-158°F).
4. Shift the selector lever to the D range.
5. Read the line pressure while the engine is idling for the D range.
6. Read the line pressure while the engine is idling for the R position and M (1GR, 2GR) range in the same manner as in Steps 4-5.
7. Stop the engine, then replace the SST (49 B019 901B) with the gauge of the SST (49 0378 400C).
8. Start the engine.
9. Firmly depress the brake pedal with the left foot.
10. Shift the selector lever to the D range.
Caution:
^ If the accelerator pedal is pressed for more than 5 s while the brake pedal is pressed, the transaxle could be damaged. Therefore, perform Steps 11 and 12 within 5 s.
11. Gradually depress the accelerator pedal with the right foot.
12. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.
13. Shift the selector lever to the N position and idle the engine for 1 min or more to cool the ATF.
14. Read the line pressure at the engine stall speed for the M (1GR, 2GR) range and R position in the same manner as in Steps 9-13.

Warning:
^ Removing the SST when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the SST, allow the ATF to cool.
15. Remove the SSTs.
16. Install a new square head plug in the inspection port.
