Nissan Versa (N17): Line pressure test

Work Procedure

INSPECTION

  1. Inspect the amount of engine oil. Replenish the engine oil if necessary. Refer to LU, "Inspection".
  2. Drive for about 10 minutes to warm up the vehicle so that the A/T fluid temperature is to 50 to 80C (122 to 176F).
  3. Inspect the amount of ATF. Replenish if necessary. Refer to TM, "Inspection".
  4. Remove fluid pressure detection plug.
  5. Install the joint pipe adapter [SST: KV31103600 ( - )], adapter [SST: 25054000 (J-25695-4)], and oil pressure gauge set (commercial service tool).

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

  6. Securely engage parking brake so that the tires do not turn.
  7. Start the engine.
  8. Measure the line pressure at both idle and the stall speed.

    CAUTION: Keep brake pedal pressed all the way down during measurement.
