DTC Description: Notes
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) provides a 5V supply and ground to the low pressure turbocharger boost pressure sensor. This sensor monitors the pressure of the compressed air exiting low pressure compressor turbocharger. The ECM interprets the signal voltage into a pressure reading. If the signal voltage is greater or less than a threshold, a fault will be set.
