EGR 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 ECM uses the EGR temperature sensor, as well as other sensors, to precisely calculate the appropriate flow and density of exhaust gas passing through either valve.
