Pressure Test

Special Tools Required 

• A/T high pressure gauge 07AAJ-PLYA100
• A/T pressure hose, 2,210 mm 07MAJ-PY4011A
• A/T pressure hose adapter 07MAJ-PY40120
• A/T oil pressure gauge set w/Panel 07406-0020400 or 07406-0020401
• A/T low pressure gauge 07406-0070300

1. Before testing, make sure the transmission fluid is filled to the proper level (see CVT FLUID LEVEL CHECK ).
2. Lift the vehicle up on a hoist, or apply parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Remove the engine under cover on the transmission side.
5. Use the following special tools. Do not allow dust or other foreign particles to enter the ports while connecting the gauges.
   NOTE:

   • Drive pulley pressure and driven pulley pressure may be above 3.43 MPa (35.0 kgf/cm² , 498 psi) when there is a transmission problem that causes the TCM to go into fail-safe mode.
   • When troubleshooting you must use the A/T high pressure gauge (07AAJ-PLYA 100) when measuring drive pulley pressure and driven pulley

6. Connect the gauge (07406-0020400 or 07406-0020401) to the reverse brake pressure inspection port (A).

7. Connect the gauge (07406-0020400 or 07406-0020401) to the forward clutch pressure inspection port (B).

8. Connect the low pressure gauge (07406-0070300) to the lubrication pressure inspection port (C).
9. Connect the commercially available oil pressure gauges (specs described in step 6) to the drive pulley pressure inspection port (D) and the driven pulley pressure inspection port (E).
10. Warm up the engine (the radiator fan comes on), then turn off the engine, and connect the tachometer.
11. Start the engine, and run it at 1,500 RPM.
12. Shift to the D position, and measure the forward clutch pressure at the forward clutch pressure inspection port (B).

    Forward Clutch Pressure 

    2001-2003 models 

    Standard: 1.40-1.75 MPa 

    1. (14.3-17.8 kgf/cm ²  , 203-253 psi) 

    2004-2006 models 

    Standard: 1.57-1.84 MPa 

    1. (16.0-18.8 kgf/cm ²  , 228-267 psi) 
13. Shift to the R position, and measure the reverse brake pressure at the reverse brake pressure inspection port (A).

    Reverse Brake Pressure 

    2001-2003 models 

    Standard: 1.40-1.75 MPa 

    1. (14.3-17.8 kgf/cm ²  , 203-253 psi) 

    2004-2006 models 

    Standard: 1.57-1.84 MPa 

    1. (16.0-18.8 kgf/cm ²  , 228-267 psi) 
14. Shift to the N position, and measure the drive pulley pressure at the drive pulley pressure inspection port (D).

    Drive Pulley Pressure 

    Standard: 0.20-0.70 MPa 

    1. (2.0-7.1 kgf/cm ²  , 29-101 psi) 
15. Measure the driven pulley pressure at the driven pulley pressure inspection port (E).

    Driven Pulley Pressure 

    Standard: 1.50-2.30 MPa 

    1. (15.3-23.5 kgf/cm ²  , 218-334 psi) 
16. Measure the lubrication pressure at the lubrication pressure inspection port (C) while holding engine speed at 3,000 RPM.

    Lubrication Pressure 

    Standard: 0.20 MPa 

    1. (2.0 kgf/cm ²  , 28 psi) or more 
17. If the measurements are out of standard, problems and probable causes are listed in the table:
    PROBLEM AND PROBABLE CAUSES
    
    

    Problem	Probable causes
    No or low forward clutch pressure	Forward clutch defective
    No or low reverse brake pressure	Reverse brake defective
    No or low drive pulley pressure	ATF pump defective PH regulator valve defective Pulley control valve A defective Pulley control valve B defective
    Drive pulley pressure too high	PH regulator valve defective Pulley control valve A defective Pulley control valve B defective CVT drive pulley pressure control valve defective
    No or low driven pulley pressure	ATF pump defective PH regulator valve defective Pulley control valve A defective Pulley control valve B defective CVT driven pulley pressure control valve defective

18. Install the sealing bolts with new sealing washers, and tighten the bolts to the specified torque.

    Torque: 18 N.m (1.8 kgf.m, 13 lbf.ft) 

    NOTE: Do not reuse old sealing washers.
19. Install the engine undercover.
