Work Procedure

WARNING: This page is about a different car, the 2019 Nissan Armada and 2018 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.
  1. START 

    Will CONSULT be used?

    Will CONSULT be used?

    YES

    GO TO 2.

    NO

    GO TO 3.

  2. PERFORM VVEL CONTROL SHAFT POSITION SENSOR ADJUSTMENT 

    SYMBOL WITH CONSULT

    1. Turn ignition switch ON.
    2. Select "VVEL POS SEN ADJ PREP" in "WORK SUPPORT" mode with CONSULT.
    3. Touch "Start" and wait a few seconds.
    4. Check that "CMPLT" is displayed on CONSULT screen.
    5. Select "VVEL POSITION SEN-B1" or "VVEL POSITION SEN-B2" in "DATA MONITOR" mode with CONSULT.
    6. Loosen the VVEL control shaft position sensor mounting bolts (1).

    7. Turn the VVEL control shaft position sensor (2) clockwise and counterclockwise while monitoring the output voltage of "VVEL POSITION SEN-B1" or "VVEL POSITION SEN-B2" and adjust the output voltage to be within the standard value.

      Voltage:

      500 ± 48 mV

    8. Tighten the VVEL control shaft position sensor mounting bolts.

      SYMBOL :

      7.0 N.m (0.71 kg-m, 62 in-lb)

    9. Reconfirm that the output voltage of "VVEL POSITION SEN-B1" or "VVEL POSITION SEN-B2" is within the standard value.

      Voltage:

      500 ± 48 mV

      NOTE: If it varies from the standard value after the mounting bolts are tightened, perform steps 6 to 8 again.
    10. Turn ignition switch OFF and wait at least 10 seconds.
    11. Start engine and warm it up to normal operating temperature.
    12. Turn ignition switch OFF and wait at least 10 seconds.
    13. Perform idle air volume learning. Refer to Description .
