HYDRAULIC TEST
1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
CAUTION:
The line pressure test should always be carried out with at least 2 people. One person should observe the condition of wheels and wheel chocks while the other is performing the test.
NOTICE:
(1) Warm up the Automatic Transmission Fluid (ATF).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Remove the test plug on the transaxle case front left side and install the SST.
SST: 09992-00095
09992-00231
09992-00271
(5) Lower the vehicle.
(6) Fully apply the parking brake and chock the 4 wheels.
(7) Connect the Techstream to the DLC3.
(8) Start the engine.
(9) Enter the following menus: Powertrain / ECT / Active Test / Control the Shift Position.
(10) Move the shift lever to D, and then use the Techstream to hold 3rd gear using Active Test. Measure the line pressure while the engine is idling.
Specified Line Pressure
Condition |
D Position kPa (kgf/cm2, psi) |
---|---|
Idling |
360 to 430 kPa (3.7 to 4.4 kgf/cm2, 52 to 62 psi) |
(11) Turn the ignition switch off.
(12) Disconnect the connector of the TCM.
HINT:
Disconnect the connector only when performing the D position stall test.
(13) Start the engine.
(14) Firmly depress the brake pedal, move the shift lever to D, depress the accelerator pedal all the way down, and check the line pressure while the stall test is performed.
Specified Line Pressure
Condition |
D Position kPa (kgf/cm2, psi) |
---|---|
Stall test |
1160 to 1350 kPa (11.8 to 13.8 kgf/cm2, 168 to 196 psi) |
(15) Turn the ignition switch off.
(16) Connect the TCM connector, depress the brake pedal firmly, move the shift lever to R, and check that the line pressure while the engine is idling and during the stall test.
Specified Line Pressure
Condition |
R Position kPa (kgf/cm2, psi) |
---|---|
Idling |
800 to 950 kPa (8.2 to 9.7 kgf/cm2, 116 to 138 psi) |
Stall test |
1900 to 2200 kPa (19.4 to 22.4 kgf/cm2, 276 to 319 psi) |
(17) Remove the SST, install the test plug.
(18) Clear the DTCs.
Evaluation
Test Result |
Possible Cause |
---|---|
Measured values are higher than the specified value in all positions |
|
Measured values are lower than the specified value in all positions |
|
Pressure is low in D only |
|
Pressure is low in R only |

Pressure Control Solenoid "A" Electrical (Shift Solenoid Valve SL1) (P0748)
DESCRIPTION
Changing from 1st to 6th is performed by the TCM turning shift solenoid valves
SL1, SL2, SL3, SL4 and SL on and off. If an open or short circuit occurs in any
of the shift solenoid valves, the TCM controls the remaining normal shift solenoid
