DTC Detection Logic
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) detected the fuel rail pressure signal voltage is greater than 4.8-VDC for more than 1 second.
NOTE:
CONSULT displays fuel supply pressure as absolute pressure. Subtract 101 kPa (1.03 Kg/cm 2
, 14.7 psi) at sea level from the CONSULT fuel supply pressure reading to approximate the gauge pressure reading.
