EGR A CONTROL

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

  • ECM detects that the current sent to the EGR volume control valve motor is equal to or more than the threshold value for 2 seconds or more under the condition that the target angle of EGR volume control valve is constant.

  • ECM detects that the difference between the target angle of EGR volume control valve and actual valve angle is equal to or more than the threshold value for 5 seconds or more.
Diagnosis delay time —

POSSIBLE CAUSE

  • EGR volume control valve

  • Foreigh objects interferes with EGR volume control valve

FAIL-SAFE

Fail safe mode Nissan Ariya Vehicle behavior
Traveling control mode Engine output control

ECM reduces the engine output, according to the rise in engine speed. This reduces the Nissan Ariya vehicle speed to encourage the driver to repair malfunction.

  • Driving at 40 km/h (25 MPH) or more is possible.

NOTE:

This value is a reference value converted from engine power to Nissan Ariya vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition.
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.
Combustion control mode Idle speed control Stops feedback control of idle speed and controls with specified speed.
Recovery speed control at decelerating Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.
Idle neutral control Stops idle neutral control.
