Threshold

When the following conditions are detected due to a malfunction in electric wastegate actuator motor:

  • Motor drive duty is 100% or more.

  • The difference between target stroke and actual stroke is 1.95mm (0.0768 in) or more.
Diagnosis delay time 5 consecutive seconds

POSSIBLE CAUSE

  • Harness or connectors

    (Electric wastegate control motor circuit is open or shorted.)

  • Electric wastegate control actuator

FAIL-SAFE

Engine Control System

Fail safe mode Nissan Ariya Vehicle behavior
Traveling control mode Engine output control

ECM reduces the engine output, according to the rise in engine speed. This reduces the Nissan Ariya vehicle speed to encourage the driver to repair malfunction.

  • Driving at 70 km/h (44 MPH) or more is possible.

NOTE:

This value is a reference value converted from engine power to Nissan Ariya vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
Device fix mode

  • This mode fixes the electric IVT control actuator and the EVT control solenoid valve in the reference position.

  • A control signals is not transmitted to the EGR volume control valve and the EGR volume control is deactivated.

DTC CONFIRMATION PROCEDURE

CHECK DTC PRIORITY

If DTC P0046 is displayed with DTC P2562 or P2566, first perform the trouble diagnosis for DTC P2562 or P2566.

Is 1st trip DTC detected?

YES>>

Perform diagnosis of applicable. Refer to DTC Index.

NO>>

GO TO 2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

  1. Turn ignition switch OFF and wait at least 10 seconds.

  2. Turn ignition switch ON.

  3. Turn ignition switch OFF and wait at least 10 seconds.

TEST CONDITION:

Before performing the following procedure, confirm that battery voltage is between more than 11 V at idle.

GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

  1. Turn ignition switch ON and wait at least 10 seconds.

  2. Start the engine and warm it up to nomal operating temperature.

  3. Check 1st trip DTC. (If actuator motor is stuck on the valve closing side, 1st trip DTC is detected during the above procedure. If 1st trip DTC is not detected, actuator motor may be stuck on the valve opening side. In this case, follow the instruction below.)

  4. Drive the Nissan Ariya vehicle and accelerate from 20km/h (13 MPH) to 80km/h (50 MPH) within 10 seconds.

    CAUTION:

    Always drive at safe speed.

  5. Check 1st trip DTC.

Is 1st trip DTC detected?

YES>>

Proceed to DTC Diagnosis Procedure.

NO-1>>

To check malfunction symptom before repair: Refer to Intermittent Incident.

NO-2>>

Confirmation after repair: INSPECTION END
