Dtc Description

DTC Description

DTC DETECTION LOGIC

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P2615	A camshaft posi signal B1 (“A” camshaft position signal output circuit low bank 1)	Diagnosis condition	Engine running at idle
		Signal (terminal)	Intake camshaft position sensor signal for electric intake valve timing control
		Threshold	The intake camshaft position sensor signal edge count is less than 2 counts per one camshaft rotation
		Diagnosis delay time	1 second

POSSIBLE CAUSE

Harness or connectors [Intake camshaft position sensor signal circuit for electric intake valve timing control is open or shorted.]

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).
Combustion control mode	Stratified charge combustion control at starting	No stratified charge combustion at starting (cold start).
	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.
Others		ECM stops the electric valve timing control. (The camshaft returns to the position of most retard angle.)

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.

CHECK INTAKE CAMSHAFT POSITION (CMP) SENSOR SIGNAL CIRCUIT FOR ELECTRIC INTAKE VALVE TIMING CONTROL

Turn ignition switch OFF.
Disconnect ECM harness connector and electric intake valve timing control module harness connector.

Check the continuity between ECM harness connector and electric intake valve timing control module harness connector.

ECM		Electric intake valve timing control module		Continuity
Connector	Terminal	Connector	Terminal	Continuity
F24	25	F80	37	Existed

Also check harness for short to power and short to ground.

Is the inspection result normal?

YES >>

INSPECTION END

NO >>

Repair or replace error-detected parts.
