(Trouble diagnosis content) 		DTC detecting condition
U0652 00

Lost communication (EGR sensor B)

(Lost Communication With EGR Sensor "B") 		Diagnosis condition Ignition switch: ON
Signal (terminal) EGR differential pressure sensor signal
Threshold ECM cannot receive the SENT communication signal from EGR differential pressure sensor.
Diagnosis delay time —

POSSIBLE CAUSE

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

  • EGR differential pressure sensor

FAIL-SAFE

Engine Control System

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 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.
