Pressure Test

Special Tools Required 

NOTE:
  • Do not test pressure for more than 10 seconds at a time.
  • Do not move the shift lever while raising the engine speed.
  • Disable the VSA by pressing the VSA OFF button.
  • VSA DTC(s) may come on during the test-drive. If the VSA DTC(s) come on, clear the DTC(s) with the HDS.
  1. Make sure the transmission fluid is filled to the proper level (see CVT FLUID LEVEL CHECK ).
  2. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported, and allow the front wheels to rotate freely.
  3. Remove the splash shield (see SPLASH SHIELD REPLACEMENT ).
  4. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.

  5. Turn the ignition switch to ON (II).
  6. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
  7. Use the recommended pressure gauge, pressure hose, and pressure hose adapter. Do not allow dust or other foreign particles to enter the holes while connecting the gauges.
    NOTE:
    • Drive pulley pressure and driven pulley pressure may be above 3, 430 kPa (34.98 kgf/cm2 , 497.5 psi) when there is a transmission problem that causes the PCM to go into fail-safe mode.
    • When troubleshooting, you must use the A/T high pressure gauge to measuring drive pulley pressure and driven pulley pressure.

    Forward Clutch Pressure 

  8. Connect the A/T oil pressure gauge set to the forward clutch pressure inspection port (A).

  12. Install the sealing bolts and new sealing washers to the pressure inspection ports, and tighten the bolts to 18 N.m (1.8 kgf.m, 13 lbf.ft). Do not reuse the old sealing washer.
  13. If the pressure is out of standard, the problem and probable causes are listed in the table.

  21. Start the engine, and warm up the engine to normal operating temperature (the radiator fan comes on twice).
  22. Shift the shift lever to N, and measure the driven pulley pressure at the driven pulley pressure inspection port while firmly pressing the brake pedal, and holding the engine speed at 1, 700 rpm.
    Pressure Standard
    Driven Pulley 830-1, 130 kPa (8.46-11.52 kgf/cm2 , 120.4-163.9 psi)
  23. Turn the engine off, then disconnect the pressure gauges from the pressure inspection ports.
  24. Install the sealing bolts and new sealing washers to the pressure inspection ports, and tighten the bolts to 18 N.m (1.8 kgf.m, 13 lbf.ft). Do not reuse the old sealing washer.
