CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P040B 00

EGR TEMP SENSOR A

(EGR temperature sensor A circuit range/performance) 		Diagnosis condition —
Signal (terminal) —
Threshold

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

  • A signal transmitted from EGR temperature sensor is 96°C (204°F) or more, even though the signal from ECT sensor is 70°C (158°F) or less.

  • A signal transmitted from EGR temperature sensor is 20°C (68°F) or less, even though warming up of the engine is performed enough and EGR control valve operates.
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.
