TURBO BOOST SENSOR

(Turbocharger/supercharger boost sensor A circuit) 		Diagnosis condition —
Signal (terminal) —
Threshold An excessively low voltage from the turbocharger boost sensor is sent to ECM.
Diagnosis delay time 5 consecutive seconds

POSSIBLE CAUSE

  • Harness or connectors

    (Turbocharger boost sensor circuit is open or shorted.)

  • Turbocharger boost sensor

  • Sensor power supply 1 circuit

FAIL-SAFE

Engine Control System

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 70 km/h (44 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.
