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 charge air cooler pressure sensor is used to measure charge air pressure entering the intake manifold. This information is used by the ECM to control emissions. The charge air cooler pressure sensor provides a voltage signal to the ECM. This sensor voltage changes, based on the pressure exiting the charge air cooler. The ECM also estimates the charge air cooler pressure. If the measured pressure differs from the estimated pressure by a calibrated amount, an error is set.
