DTC Detection Logic

WARNING: This page is about a different car, the 2018 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

ECM detects an abnormal voltage in the intake valve timing control solenoid valve control circuit.
ECM detects an abnormal voltage in the intake valve timing intermediate lock control solenoid valve control circuit.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0075	INT/V TIM V/CIR-B1 (Intake valve control solenoid circuit bank 1)	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	Voltage signal transmitted from intake valve timing control solenoid valve to ECM Voltage signal transmitted from intake valve timing intermediate lock control solenoid valve to ECM
		Threshold	ECM detects an abnormal voltage in the intake valve timing control solenoid valve control circuit. ECM detects an abnormal voltage in the intake valve timing intermediate lock control solenoid valve control circuit.
