GO TO 2.

CHECK A/F SENSOR FUNCTION

With CONSULT

  1. Start engine and warm it up to normal operating temperature.

  2. Select “A/F SEN1 (B1)” in “DATA MONITOR” mode of “ENGINE” using CONSULT.

  3. Check “A/F SEN1 (B1)” indication.

With GST

Follow the procedure “With CONSULT” above.

Is the indication constantly approx. 0 V?

YES>>

Proceed to DTC Diagnosis Procedure

NO>>

GO TO 3.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

  1. Turn ignition switch OFF, wait at least 10 seconds and then restart engine.

  2. Drive and accelerate Nissan Ariya vehicle to more than 40 km/h (25 MPH) within 20 seconds after restarting engine.

    CAUTION:

    Always drive Nissan Ariya vehicle at a safe speed.

  3. Maintain the following conditions for about 20 consecutive seconds.

    ENG SPEED 1,000 - 3,200 rpm
    VHCL SPEED SE More than 40 km/h (25 mph)
    B/FUEL SCHDL 1.5 - 9.0 msec
    Selector lever Suitable position

    NOTE:

    • Keep the accelerator pedal as steady as possible during the cruising.

    • If this procedure is not completed within 1 minute after restarting engine at step 1, return to step 1.

  4. Check 1st trip DTC.

With GST

Follow the procedure “With CONSULT” above.

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

DTC Diagnosis Procedure

CHECK AIR FUEL RATIO (A/F) SENSOR 1 POWER SUPPLY

  1. Turn ignition switch OFF.

  2. Disconnect A/F sensor 1 harness connector.

  3. Turn ignition switch ON.

  4. Check the voltage between A/F sensor 1 harness connector and ground.
