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 the Injector low side driver is shorted to another injector or a high side driver.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0276-00	CYL6 INJECTOR (Cylinder 6 Injector Circuit Low)	Diagnosis condition	Engine running
		Signal (terminal)	(-)
		Threshold	Actuator charging time ≤ 100 secs Actuator charging time for cylinder number 6 ≥ 5 secs Differential current in the injector shunt for current measurement and difference analysis ≤ 9.8A Maximum injector current ≤ 32A Injector buffer current during voltage discharging ≤ 9.6A Or Actuator charging time ≤ 100 secs Actuator charging time for cylinder number 6 ≥ 5 secs Differential current in the injector shunt for current measurement and difference analysis ≤ 9.8A Actuator discharge voltage < injector charge voltage set-point 0.55V Actuator charge up voltage for cylinder number 6 < injector charge voltage set point +80V Actuator charge up voltage for cylinder number 6 < injector charge voltage set point 0.7V Actuator charge up voltage for cylinder number 6 < injector charge voltage set point 0.55V Maximum injector current ≤ 32A Injector buffer current during voltage discharging ≤ 9.6A
		Diagnosis delay time	Diagnostic runs continuously when the engine is running
