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 battery or a voltage source.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P02F2-00	(Cylinder 5 Injector Circuit Range/Performance)	Diagnosis condition	Engine running
		Signal (terminal)	(-)
		Threshold	Actuator charging time ≤ 100 secs Actuator charging time for cylinder number 5 ≥ 5 secs Differential current in the injector shunt for current measurement and difference analysis ≤ 9.8A Injector buffer current during voltage discharging ≤ 9.6A
		Diagnosis delay time	Diagnostic runs continuously when the engine is running
