Engine Charge Air Cooler Outlet Pressure/Temperature Sensor
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 charge air cooler outlet pressure/temperature sensor monitors the temperature and pressure of air in the intake air duct.
The sensor information is used by the ECM to determine air filter restriction, changes in altitude, help determine air volume entering the engine and manage engine operation.
