Exhaust Gas Pressure 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 exhaust gas pressure sensor is remotely located at the back left corner of the air intake manifold. The sensor is mounted in a tube that reads exhaust gas pressure from the left exhaust manifold. The exhaust gas pressure sensor is used as an input for rotary turbine control valve positioning during cold start and is also used to assist in thermal management for the after treatment system. In addition, the exhaust gas pressure sensor is used by the ECM as one of the inputs to determine the quantity of EGR flow.
