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 fuel rail pressure sensor using a dedicated sensor supply circuit. The pressure sensor delivers a fuel pressure signal to the ECM of the fuel rail. During engine operating conditions, the ECM commands and monitors the fuel rail pressure. If the fuel rail pressure exceeds or falls below commanded pressure, a DTC will set.
