DTC Description

DTC DETECTION LOGIC

DTC

CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P044C 00

EGR SENSOR C

(EGR sensor C circuit low) 		Diagnosis condition Ignition switch ON
Signal (terminal) EGR volume control valve signal
Threshold

ECM detects the following status continuously for 5 seconds or more:

A voltage signal transmitted from the EGR volume control valve position sensor shows too low.
Diagnosis delay time 5 seconds or more

POSSIBLE CAUSE

  • Harness or connectors

    (EGR volume control valve position sensor circuit is open or shorted.)

  • EGR volume control valve

FAIL-SAFE

Fail safe mode Nissan Ariya Vehicle behavior
Traveling control mode Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

NOTE:

ECM does not control the accelerator pedal releasing speed.
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

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.

GO TO 2.

PERFORM DTC CONFIRMATION PROCEDURE

  1. Turn ignition switch ON and wait at least 5 seconds.

  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 VOLUME CONTROL VALVE POSITION SENSOR POWER SUPPLY

  1. Turn ignition switch OFF.

  2. Disconnect EGR volume control valve harness connector.

  3. Turn ignition switch ON.

  4. Check voltage between EGR volume control valve harness connector and ground.
