DTC Detection Logic

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

The Engine Control Module (ECM) detected an open circuit in the engine wiring harness or injector actuator.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0208-00	CYL8 INJECTOR (Injector Circuit/Open - Cylinder 8)	Diagnosis condition	Engine running
		Signal (terminal)	(-)
		Threshold	Actuator charging time ≤ 100 secs Actuator charging time for cylinder number 8 < 5 secs Differential current in the injector shunt for current measurement and difference analysis ≤ 9.8A Actuator discharge time for cylinder number 8 ≥ 35.2 secs Actuator charge up voltage for cylinder number 8 ≤ injector charge voltage set point +80V Differential current in the injector buffer shunt for current measurement and difference analysis ≤ 9.8A Maximum injector current ≤ 32A Injector buffer current during voltage discharging ≤ 9.6A Or all of the following: Actuator charging time for cylinder number 8 ≥ 5 secs Actuator discharge time for cylinder number 8 ≤ 35.2 secs Actuator charge up voltage for cylinder number 8 > injector charge voltage set point +80V Differential current in the injector shunt for current measurement and difference analysis ≤ 9.8A Maximum injector current ≤ 32A Injector buffer current during voltage discharging ≤ 9.8A
		Diagnosis delay time	Diagnostic runs continuously when the engine is running
