CONSULT screen terms

(Trouble diagnosis content) 		DTC detection condition
P0103 00

MAF SEN/CIRCUIT-B1

(Mass or volume air flow sensor "A" circuit high) 		Diagnosis condition

  • Turn ignition switch ON

  • Engine running at idle
Signal (terminal) Mass air flow sensor signal
Threshold An excessively high voltage from the sensor is sent to ECM
Diagnosis delay time 5 seconds

POSSIBLE CAUSE

  • Mass air flow sensor

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.
Combustion control mode Ignition timing correction control Partially controls ignition timing control.
Retardation control Controls ignition timing delay control in the intermediate water temperature range.

Stop/Start System

When a DTC is detected, the stop/start indicator lamp blinks slowly and the stop/start system operation is prohibited.

When ECM detects error while operating the stop/start system, ECM restarts the engine.
