DTC Description

DTC DETECTION LOGIC

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0365	CMP SEN/CIRC-B1 (Camshaft position sensor “B” circuit bank 1)	Diagnosis condition	Engine: Cranking or running (idle speed or more than 800 rpm)
		Signal (terminal)	EVT control position sensor signal
		Threshold	EVT control position sensor signal is not sent to ECM during engine cranking EVT control position sensor signal is not sent to ECM during engine running The pulse signal sent from the EVT control position sensor to ECM is not in the normal pattern during engine running
		Diagnosis delay time	—

Possible Cause

Harness or connectors
- Exhaust camshaft position sensor circuit is open or shorted.
- Sensor power supply 1 circuit is shorted.
Exhaust camshaft position sensor
Exhaust camshaft
Starter motor
Starting circuit
Battery deterioration
Sensor power supply 1 circuit sensors

FAIL-SAFE

Engine Control System

Engine operating condition in fail-safe mode
Fail safe mode		Nissan Sentra Vehicle behavior
Device fix mode		This mode fixes the electric IVT motor and the EVT control solenoid valve in the reference position. The intake manifold runner control valve motor is turned OFF (intake manifold runner control valve opens).

Idle Start/Stop System

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

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

Confirmation Procedure

Confirmation Procedure
