DTC

CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P040C 00

EGR TEMP SENSOR A

(EGR temperature sensor A circuit low) 		Diagnosis condition —
Signal (terminal) —
Threshold ECM detects that a voltage signal from EGR temperature sensor is less than 0.04 V for 5 consecutive seconds.
Diagnosis delay time —

POSSIBLE CAUSE

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

  • EGR temperature 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.

CHECK EGR TEMPERATURE SENSOR

With CONSULT

  1. Turn ignition switch ON.

  2. Select “EGR TEMP SEN” in “DATA MONITOR” mode of “ENGINE” using CONSULT.

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

  4. Check that “EGR TEMP SEN” indication as follows.

    Monitor item Condition Value
    EGR TEMP SEN

    • Warm-up condition

    • Idle speed

    		 1,100 – 4,500 mV

Without CONSULT

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

  2. Check that voltage between ECM harness connector terminals as follows.

    ECM Condition Voltage
    Connector + Connector −
    Terminal Terminal
    F71 104 F71 102

    • Warm-up condition

    • Idle speed

    		 1.1 – 4.5 V

Is the inspection result normal?

YES>>

GO TO 3.

NO>>

Replace EGR temperature sensor. Refer to Exploded View.

CHECK EGR TEMPERATURE SENSOR POWER SUPPLY

  1. Turn ignition switch OFF.

  2. Disconnect EGR temperature sensor harness connector.

  3. Turn ignition switch ON.

  4. Check the voltage between EGR temperature sensor harness connector terminal and ground.
