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 engine charge air cooler outlet pressure/temperature sensor reading was higher or lower than estimated during engine running or after an 8 hour cold soak.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P007B-00	(Charge Air Cooler Temperature Sensor Circuit Range/Performance)	1	Diagnosis condition	Engine running.
			Signal (terminal)	(-)
			Threshold	Cumulative sum of error in 30 seconds is > 18, 000°C, which is ≥ 24°C. Where tolerance is defined as 0°C.
			Diagnosis delay time	Diagnostic runs continuously when the engine is running
		2	Diagnosis condition	8 hour cold soak Engine running.
			Signal (terminal)	(-)
			Threshold	Engine charge air cooler outlet pressure/temperature sensor is 13°C > then the tolerance of the second most accurate sensor of the remaining sensors
			Diagnosis delay time	Diagnostic runs continuously when the engine is running
