ABSL PRES SEN/CIRC

(Manifold Absolute Pressure/Barometric Pressure Sensor Circuit High) 		Diagnosis condition Ignition switch ON
Signal (terminal) Manifold absolute pressure (MAP) sensor signal
Threshold An excessively high voltage from the sensor is sent to ECM
Diagnosis delay time —

POSSIBLE CAUSE

  • Harness or connectors [Manifold absolute pressure (MAP) sensor circuit is open or shorted.]

  • Manifold absolute pressure (MAP) sensor

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 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.

DTC CONFIRMATION PROCEDURE

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
