EGR temperature sensor A

(Mutual Comparison to Other Temperature Sensors) 		Diagnosis condition Engine running
Signal (terminal) —
Threshold The comparison result of signals transmitted to ECM from each temperature sensor (EGT sensor, ECT　sensor, FTT sensor, and IAT sensor) shows that the temperature of the EGR temperature sensor is higher/lower than that of other temperature sensors when the engine is started with its cold state.
Diagnosis delay time 300 seconds

POSSIBLE CAUSE

  • Harness or connectors (High or low resistance in EGR temperature sensor circuit)

  • 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.
