Diagnosis Procedure

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.
  1. CHECK INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)
    1. Start engine.
    2. Check voltage between TCM connector terminals.

    3. If OK, check the pulse when vehicle drive.
    TERMINAL VOLTAGE REFERENCE

    TCM connector Condition Voltage (Approx.)
    Connector Terminal
    F15 33 When driving ["M1" position, 20 km/h (12 MPH)] 595 Hz

    Is the inspection result normal? 

    YES: GO TO 7.

    NO - 1: Battery voltage is not supplied: GO TO 2.

    NO - 2: Battery voltage is supplied, but there is a malfunction in the frequency: GO TO 4.

  6. CHECK THE TCM SHORT
    1. Replace with the same type of TCM. Refer to "EXPLODED VIEW ".
    2. Connect each connectors.
    3. Perform "DTC CONFIRMATION PROCEDURE". Refer to "DTC LOGIC ".

    Is the "P0715 INPUT SPD SEN/CIRC" detected again? 

    YES: GO TO 7.

    NO: Refer to "INTERMITTENT INCIDENT ".

  7. DETECT MALFUNCTIONING ITEMS

    Check TCM connector pin terminals for damage or loose connection with harness connector.

    Is the inspection result normal? 

    YES: Replace TCM. Refer to "EXPLODED VIEW ".

    NO: Repair or replace damaged parts.
