DTC

CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P0486 00

EGR SENSOR B

(EGR sensor B circuit) 		Diagnosis condition —
Signal (terminal) —
Threshold ECM detects that a voltage signal from EGR differential pressure sensor is less than 0.5 V for 5 consecutive seconds.
Diagnosis delay time —

POSSIBLE CAUSE

  • Harness or connectors (EGR differential pressure sensor circuit is open or shorted.)

  • EGR differential pressure sensor

FAIL-SAFE

Fail safe mode Nissan Ariya Vehicle behavior
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

  • P06B0

  • P06B3

If applicable DTC detected?

YES>>

Perform diagnosis of applicable.

  • DTC P06B0: Refer to DTC Description.

  • DTC P06B3: Refer to DTC Description.

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 10 V or more at ignition switch ON.

  2. 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

DTC Diagnosis Procedure

CHECK EGR DIFFERENTIAL PRESSURE SENSOR POWER SUPPLY

  1. Turn ignition switch OFF.

  2. Disconnect EGR differential pressure sensor harness connector.

  3. Turn ignition switch ON.

  4. Check the voltage between EGR differential pressure sensor harness connector and ground.
