DTC Detection Logic

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD and 2019 Nissan NV2500 HD. However, it is still accessible from the selected car via links, so may be relevant.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0190	FUEL PRES SEN/CIRCUIT (Fuel rail pressure sensor "A" circuit)	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	Fuel rail pressure sensor signal
		Threshold	Signal voltage from the fuel rail pressure sensor remains at more than 4.84 V / less than 0.2 V
		Diagnosis delay time	5 seconds or more
P0192	FRP SEN/CIRC (Fuel rail pressure sensor "A" circuit low)	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	Fuel rail pressure sensor signal
		Threshold	Signal voltage from the fuel rail pressure sensor remains at less than 0.37 V
		Diagnosis delay time	5 seconds or more
P0193	FRP SEN/CIRC (Fuel rail pressure sensor "A" circuit high)	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	Fuel rail pressure sensor signal
		Threshold	Signal voltage from the fuel rail pressure sensor remains at more than 3.46 V
		Diagnosis delay time	5 seconds or more
