Line Pressure Test Procedure

  1.  Inspect the amount of engine oil and replenish if necessary.

  2.  Drive the car for about 10 minutes to warm it up so that the CVT fluid reaches in the range of 50 to 80C (122 to 176F). Then inspect the amount of CVT fluid and replenish if necessary.

    NOTE: The CVT fluid temperature rises in the range of 50 to 80C (122 to 176F) during 10 minutes of driving.

  3.  After warming up transaxle assembly, remove oil pressure detection plug and install Tool.

CAUTION: When using oil pressure gauge, be sure to use O-ring attached to oil pressure detection plug.

4. Securely engage parking brake so that the tires do not turn.

5. Start the engine, and then measure the line pressure at both idle and the stall speed.

CAUTION:

  •  Keep brake pedal pressed all the way down during measurement.

  •  When measuring the line pressure at the stall speed.
