Line Pressure Test: Notes

Purpose of this test is to check operating conditions of each part by measuring fluid pressure in fluid pressure line.

Line pressure test requires the following conditions.

• CVT fluid is at normal operating temperature (70 - 80 °C/158 - 176 °F).
• CVT fluid is replenished to proper level (between full and low on dipstick).
• A/C switch is turned OFF.

1. Check CVT fluid level.
2. Apply parking brake securely and place chocks against wheels.
3. Remove fluid pressure check hole bolt (1).
4. Attach oil pressure gauge to fluid pressure check hole (2) in transaxle case.
   CAUTION: After attaching oil pressure gauge, check that no fluid leakage exists.

5. Depress foot brake fully, run engine at idle and stall then check fluid pressure in "D" or "R" range.
   CAUTION:

   • Do not continue running engine at stall speed longer than 5 seconds.
   • After performing line pressure test, be sure to leave engine running at idle for longer than one minute before performing another line pressure test.

   	"D" range	"R" range
   At idle speed	0.75 MPa (7.6 kgf/cm2 , 108 psi, 7.5 bar)
   At stall speed (Reference)	Approx. 5.0 MPa (5.1 kgf/cm2 , 725 psi, 50 bar)

6. If check result is OK, disconnect special tool, then tighten fluid pressure check hole bolt to specified torque.
