Inspection and Judgment: Inspection

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

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 80°C (122 to 176°F). Then inspect the amount of CVT fluid and replenish if necessary.
    NOTE: The CVT fluid temperature rises in the range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
  3. After warming up transaxle assembly, remove oil pressure detection plug and install Tool.

    Tool number: - (OTC3492) 

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

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

    • When measuring the line pressure at the stall speed. Refer to "INSPECTION AND JUDGMENT ".

    Line pressure: Refer to  "LINE PRESSURE ".

  6. Install oil pressure detection plug and tighten to the specified torque below after the measurements are complete.

    Oil pressure detection plug: 7.5 N.m (0.77 kg-m, 66 in-lb) 

    CAUTION:
    • Never reuse O-ring.
    • Apply CVT fluid to O-ring.
